feat: user invite flow, deactivate/delete, favicon, dashboard loading fix, admin full-width

- Invite flow: admin can invite users by email with role selection; accept-invite page
  sets password and creates the account; 72-hour token expiry; E2E tests
- User deactivate/reactivate/delete: new tRPC procedures + UI buttons; deactivation
  revokes all active sessions immediately; delete cascades vacation/broadcast records;
  isActive field added via migration 20260402000000_user_isactive
- Auth: block login for inactive users with audit entry
- Favicon: SVG favicon + ICO/PNG fallbacks (16, 32, 180, 192, 512px); manifest updated
- Dashboard: GridLayout dynamic-import loading skeleton prevents blank dark area
  on first login before react-grid-layout chunk is cached
- Admin users: remove max-w-5xl constraint so table uses full page width
- Dev: docker container restart workflow documented in LEARNINGS.md; Prisma generate
  must run inside the container after schema changes (named node_modules volume)
