feat: complete Epic 1 — team management & permission system

- Story 1.1: Permission enum, config, AuthorizesPermissions & HasWorkspaceScope traits, member→worker migration
- Story 1.2: Team page with member list, invitation system with queued email
- Story 1.3: Role assignment (Manager/Worker) and member removal with activity logging
- Story 1.4: Owner-only permission toggle matrix for Managers (manage team, view logs, configure portal)
- Story 1.5: Role-based access enforcement — Workers see only assigned declarations/clients, sidebar scoping
- Story 1.6: Workspace switcher dropdown for multi-workspace users with session-based switching
- 83 new/modified files, 182 tests passing with zero regressions
