[CLAUDE] Office: P11-D ItTicket admin reassign-UI + P11-E AttendanceReport menu-key

Task C - ItTicket admin reassign-UI (fe-admin only):
- Per-card reassign dialog on ItTicketsPage kanban (admin override of round-robin auto-assign).
- Reuses existing PUT /it-tickets/{id}/assign (Admin-only) + GET /users picker. No new BE endpoint.
- fe-admin intentionally diverges from fe-user (read-only) — admin-management action.

Task D - AttendanceReport menu-key (P11-E promote, no migration):
- MenuKeys.OffAttendanceReport 'Báo cáo chấm công' leaf under Văn phòng số (order 8), Admin-perm auto via All[].
- DbInitializer idempotent seed + fe-admin menuKeys.ts/Layout staticMap -> existing /attendance/report route.

Pipeline: implementer-backend -> implementer-frontend -> reviewer (PASS, 0 issues). dotnet+npm builds clean. Tests 203 (unchanged - no new BE logic/schema).
