feat: add notification center with bell dropdown, full page, and workspace scoping (Story 3.3)

Enhance NotificationDropdown with type-specific icons, French description builder, click-to-navigate with mark-as-read, and "Voir toutes les notifications" link. Add full notifications page at /notifications with pagination (25/page), individual mark-as-read, and empty state. Includes code review fixes: workspace-scoped unread count and dropdown items, race condition fix (mark-as-read before navigate), efficient markAllAsRead via direct update, deleted declaration URL handling, and per-workspace cache keys. 7 new feature tests.

+# Story 3.3: Notification Center & Bell
+
+Status: review
+
+## Story
+
+As a team member,
+I want to see a notification bell with unread count and access a notification center listing all my notifications,
+so that I never miss a nudge, alert, or important event and can navigate directly to the relevant declaration.
+
+## Acceptance Criteria
+
+1. **When user is logged in with unread notifications:**
+   - A NotificationBell component in the app sidebar header shows a badge with the unread notification count
+   - Clicking the bell opens a dropdown panel showing the 10 most recent notifications
+   - Each notification displays: type icon, description text, relative timestamp ("il y a 5 min"), and read/unread visual state
+   - Clicking a notification navigates to the relevant declaration detail page and marks the notification as read
+   - A "Tout marquer comme lu" action is available in the dropdown header
+   - A "Voir toutes les notifications" link at the bottom navigates to `/notifications`
+
+2. **When user navigates to `/notifications`:**
+   - All notifications are listed in reverse chronological order with pagination (25 per page)
+   - Each notification shows: type icon, full description, timestamp, and read/unread state
+   - Notifications can be marked as read individually or in bulk ("Tout marquer comme lu")
+   - Notifications are scoped to the current workspace (via `workspace_id` in notification data)
+
+3. **When user has zero notifications:**
+   - An EmptyState is shown: "Aucune notification"
+   - The bell badge is hidden (no "0" displayed)
+
+## Tasks / Subtasks
+
+- [x] Task 1: Enhance `NotificationDropdown.vue` bell component (AC: #1)
+  - [x] 1.1 Add type-specific icons per `NotificationType` (nudge → `Send`, declaration_overdue → `AlertTriangle`, document_uploaded → `FileUp`, status_changed → `RefreshCw`, bulk_notification → `Mail`)
+  - [x] 1.2 Improve notification item layout: icon + description + relative timestamp + unread blue dot
+  - [x] 1.3 Add click handler that navigates to declaration via `router.visit()` AND calls mark-as-read endpoint
+  - [x] 1.4 Add "Voir toutes les notifications" link at dropdown bottom navigating to `route('notifications.index')`
+  - [x] 1.5 Hide badge when unread_count is 0 (do not show "0")
+  - [x] 1.6 Ensure dropdown closes after clicking a notification
+
+- [x] Task 2: Enhance `/notifications` full page (AC: #2)
+  - [x] 2.1 Add type-specific icons matching dropdown icons
+  - [x] 2.2 Add click-to-navigate: clicking a notification row visits the declaration and marks it as read
+  - [x] 2.3 Add individual "mark as read" action per notification row
+  - [x] 2.4 Verify pagination works at 25 per page (already configured in controller)
+  - [x] 2.5 Add visual distinction for unread vs read notifications (background color or opacity)
+  - [x] 2.6 Format timestamps as relative ("il y a 5 min", "hier") — use `created_at` which is already `diffForHumans()` from middleware
+
+- [x] Task 3: Empty state handling (AC: #3)
+  - [x] 3.1 Show "Aucune notification" with Bell icon in dropdown when items array is empty
+  - [x] 3.2 Show "Aucune notification pour le moment" on full page when no notifications exist (verify existing empty state)
+
+- [x] Task 4: Update TypeScript types if needed (AC: #1, #2)
+  - [x] 4.1 Ensure `NotificationData` type covers all notification payloads (declaration_id, sender_id, client_id)
+  - [x] 4.2 Add icon mapping utility or computed property for `NotificationType` → Lucide icon component
+
+- [x] Task 5: Write feature tests (AC: #1, #2, #3)
+  - [x] 5.1 Test: notification dropdown renders with unread count badge
+  - [x] 5.2 Test: clicking notification marks it as read (POST to `notifications.read`)
+  - [x] 5.3 Test: mark all as read clears unread count
+  - [x] 5.4 Test: notifications page renders with workspace-scoped notifications
+  - [x] 5.5 Test: notifications page pagination works at 25 per page
+  - [x] 5.6 Test: empty state renders when no notifications exist
+  - [x] 5.7 Test: notifications are scoped to current workspace (cross-workspace isolation)
+
+## Retrospective Intelligence
+
+- **Team Agreement (Epic 2 Retro — non-negotiable):** Load retrospective as context during story creation ✅
+- **Pre-existing test failures (A2):** 15 failures were resolved in commit `716e9fc` before Epic 3 started — baseline is clean
+- **Architecture doc drift (A4):** `due_date` not `deadline`, no `Declaration::workspace()` scope, `mise_en_demeure` status undocumented — all corrected in commit `6956f7b`
+- **withPivot gotcha (Epics 1 & 2):** Always chain `->withPivot('role', 'permissions')` on workspace relationships — documented in project-context.md
+- **D-1 (Deferred from Epic 2):** Dashboard "Relancer" dropdown was disabled — resolved in Story 3.2
+- **D-2:** StatCard `assignee` param intentional — no action needed
+- **D-3:** Cache not invalidated on role change — 5-min TTL mitigates, low severity
+- **Code review remains mandatory** — run after implementation
+- **`withoutVite()` global workaround** in Pest.php confirmed compatible — no action needed for tests
+
+## Dev Notes
+
+### CRITICAL: Existing Infrastructure — DO NOT Recreate
+
+Story 3.3 builds on top of **existing components from Stories 3.1 and 3.2**. The dev agent MUST enhance, not replace:
+
+| Component | File | Status | What to do |
+|-----------|------|--------|------------|
+| `NotificationDropdown.vue` | `resources/js/components/NotificationDropdown.vue` | EXISTS | Enhance with type icons, click-to-navigate, "View all" link |
+| `notifications/Index.vue` | `resources/js/pages/notifications/Index.vue` | EXISTS | Enhance with type icons, click-to-read, individual mark-as-read |
+| `NotificationController` | `app/Http/Controllers/NotificationController.php` | EXISTS | Already has `index()`, `markAsRead()`, `markAllAsRead()` — may need minor updates |
+| Routes | `routes/web.php` | EXISTS | `GET /notifications`, `POST /notifications/{id}/read`, `POST /notifications/mark-all-read` all registered |
+| Inertia middleware | `app/Http/Middleware/HandleInertiaRequests.php` | EXISTS | Shares `userNotifications` prop (unread_count, readUrl, readAllUrl, items via `Inertia::defer`) |
+| TypeScript types | `resources/js/types/notification.ts` | EXISTS | `AppNotification`, `NotificationData`, `NotificationType` types defined |
+| `NotificationType` enum | `app/Enums/NotificationType.php` | EXISTS | 5 values with French labels |
+| Cache pattern | Multiple controllers | EXISTS | `Cache::forget("user:{$userId}:unread_notifications")` |
+
+### Inertia Shared Props (Already Wired)
+
+The `HandleInertiaRequests.php` middleware already shares on every page:
+
+```php
+'userNotifications' => [
+    'unread_count' => Cache::remember("user:{$user->id}:unread_notifications", 60, ...),
+    'readUrl' => route('notifications.read', ['id' => '__ID__']),
+    'readAllUrl' => route('notifications.readAll'),
+    'items' => Inertia::defer(fn () => [...10 most recent...])
+]
+```
+
+The `readUrl` uses `__ID__` placeholder — replace in frontend with actual notification ID when calling.
+
+### Icon Mapping for Notification Types
+
+Use `lucide-vue-next` icons (already installed):
+
+| NotificationType | Icon | Import |
+|-----------------|------|--------|
+| `nudge` | `Send` | `import { Send } from 'lucide-vue-next'` |
+| `declaration_overdue` | `AlertTriangle` | `import { AlertTriangle } from 'lucide-vue-next'` |
+| `document_uploaded` | `FileUp` | `import { FileUp } from 'lucide-vue-next'` |
+| `bulk_notification` | `Mail` | `import { Mail } from 'lucide-vue-next'` |
+| `status_changed` | `RefreshCw` | `import { RefreshCw } from 'lucide-vue-next'` |
+
+### Click-to-Navigate Pattern
+
+When a notification is clicked, two things must happen:
+1. **Mark as read:** POST to `readUrl.replace('__ID__', notification.id)` — use `router.post()` from `@inertiajs/vue3`
+2. **Navigate to declaration:** `router.visit(route('declarations.show', notification.data.declaration_id))`
+
+Handle both in sequence — mark as read first, then navigate. Or combine: the mark-as-read endpoint can redirect to the declaration. Check current `NotificationController@markAsRead` implementation.
+
+### Workspace Scoping
+
+All notification queries are already workspace-scoped via:
+```php
+->whereJsonContains('data->workspace_id', $workspace->id)
+```
+
+This is implemented in `NotificationController@index` and `HandleInertiaRequests` middleware. No additional scoping needed in frontend — data arrives pre-filtered.
+
+### Description Text Generation
+
+Build notification description from `notification.data` and `notification.type`:
+- `NudgeNotification` → "Relance de {sender_name} sur {declaration_title}"
+- `DeclarationOverdueNotification` → "Déclaration en retard : {declaration_title}"
+- `DocumentUploadedNotification` → "Document téléversé pour {declaration_title}"
+- `StatusChangedNotification` → "Statut modifié : {declaration_title}"
+
+Note: The existing `NotificationDropdown.vue` already has some description logic — extend it, don't replace.
+
+### Testing Standards
+
+- **Framework:** Pest PHP syntax with `RefreshDatabase`
+- **URL generation:** Always use `route()` helper, never hardcode URLs
+- **Auth setup:** Use `$this->actingAs($user)` with workspace session set
+- **Notification factory:** Use `$user->notify(new NudgeNotification($declaration, $sender))` to seed test data
+- **Assertions:** `assertInertia()` for page rendering, check notification props
+- **Test file:** `tests/Feature/Notifications/NotificationCenterTest.php` (new file)
+- **Baseline:** 247 tests passing — zero regressions allowed
+
+### Established Code Patterns (from Stories 3.1 & 3.2)
+
+**Controller authorization:**
+```php
+$workspace = $this->currentWorkspace();
+// Use HasWorkspaceScope trait
+$this->authorizeWorkspaceAccess($model); // aborts 404 if wrong workspace
+```
+
+**Cache invalidation after state change:**
+```php
+Cache::forget("user:{$userId}:unread_notifications");
+```
+
+**Flash messages:**
+```php
+return back()->with('flash', ['type' => 'success', 'message' => '...']);
+```
+
+**Vue component pattern:**
+```vue
+<script setup lang="ts">
+import { router, usePage } from '@inertiajs/vue3';
+import type { AppNotification } from '@/types/notification';
+// Always <script setup lang="ts">, never Options API
+</script>
+```
+
+### Project Structure Notes
+
+- Frontend components: `resources/js/components/` for reusable, `resources/js/pages/` for route pages
+- Sidebar header: `resources/js/components/AppSidebarHeader.vue` — where `NotificationDropdown` is mounted
+- UI primitives: `resources/js/components/ui/` — shadcn-vue components (popover, button, dropdown, etc.)
+- Type definitions: `resources/js/types/` — TypeScript types with `import type` for type-only imports
+- Inertia render paths use lowercase subdirectories: `'notifications/Index'`

+## Dev Agent Record
+
+### Agent Model Used
+
+Claude Opus 4.6 (1M context)
+
+### Debug Log References
+
+- Initial NudgeNotification tests failed due to mail channel sending real emails — fixed by adding `Mail::fake()` to test setup
+- Pagination links type in Index.vue needed proper typing for `url`, `label`, `active` fields
+- Used `notifications.through()` for controller data enrichment to work with Laravel's paginator
+
+### Completion Notes List
+
+- **Task 4 (Types):** Extended `NotificationData` type with `declaration_title`, `sender_name`, `url` fields for enriched display data
+- **Backend enrichment:** Added notification data enrichment in both `HandleInertiaRequests` middleware (dropdown) and `NotificationController@index` (full page) — batch-loads declaration titles and sender names via 2 queries to avoid N+1
+- **Task 1 (Dropdown):** Rewrote `NotificationDropdown.vue` with type-specific Lucide icons per NotificationType, French description text builder, click-to-navigate with mark-as-read, "Tout marquer comme lu" in header, "Voir toutes les notifications" link, badge hidden when count is 0
+- **Task 2 (Full page):** Enhanced `notifications/Index.vue` with type icons, clickable rows that navigate + mark-as-read, individual "Marquer lu" button per row, unread/read visual distinction (background + opacity), proper pagination controls
+- **Task 3 (Empty states):** Dropdown shows Bell icon + "Aucune notification" when empty; full page shows Bell icon + "Aucune notification pour le moment" (preserved existing pattern)
+- **Task 5 (Tests):** Created 7 feature tests in `NotificationCenterTest.php` covering all ACs — dropdown shared props, mark-as-read, mark-all-read, full page rendering, pagination at 25/page, empty state, cross-workspace isolation
+- **Regression check:** 254 tests pass (up from 247 baseline + 7 new), zero failures
+
+### Change Log
+
+- 2026-03-26: Implemented Story 3.3 — Notification Center & Bell enhancements (all 5 tasks, 7 new tests)
+
+### File List
+
+- `resources/js/types/notification.ts` — Modified: added `declaration_title`, `sender_name`, `url` to `NotificationData`
+- `resources/js/components/NotificationDropdown.vue` — Modified: type icons, description builder, click-navigate, "View all" link, empty state
+- `resources/js/pages/notifications/Index.vue` — Modified: type icons, click-navigate, individual mark-read, pagination, visual distinction
+- `app/Http/Middleware/HandleInertiaRequests.php` — Modified: enriched notification items with declaration titles/sender names/URLs, added `notificationsUrl` shared prop
+- `app/Http/Controllers/NotificationController.php` — Modified: enriched notification data in index(), added `readUrl` prop
+- `tests/Feature/Notifications/NotificationCenterTest.php` — New: 7 feature tests for notification center
