feat: add one-click nudge system with popover, throttling, and email notifications (Story 3.2)

Add NudgeController with 1-hour throttling per declaration, NudgePopover component
on declarations index and dashboard, shadcn-vue popover primitives, and per-declaration
nudge tracking. Owners/managers can nudge assigned workers with one click.
Includes 10 feature tests covering authorization, throttling, and cache invalidation.
