Add Morning Routine to Admin and TV greeting state

Adds a per-user Morning Routine item list that appears in the TV
dashboard Activities panel during the "Good Morning" countdown
(before the first block starts).

- morning_routine_items table (auto-created on startup)
- CRUD API at /api/morning-routine (auth-required)
- Items included in the public DashboardSnapshot so TV gets them
  without auth
- Morning Routine section in Admin page (same add/edit/delete UX
  as subject options)
- TV Activities column shows routine items when no block is active,
  switches to subject options once a block starts
