riyadhafraa ada3ef6264 Add admin trend stats and sign-up sparkline ...

Task #13: Show admin trends like new sign-ups this week.

Backend
- Added GET /api/stats/admin (admin-only) in artifacts/api-server/src/routes/stats.ts.
- Returns: newUsersLast7Days, newUsersPrev7Days, activeServices,
  inactiveServices, signupsByDay (7-day series with zero-filled days,
  computed via date_trunc on usersTable.createdAt).

API spec / codegen
- Added /stats/admin path and AdminStats schema in lib/api-spec/openapi.yaml.
- Re-ran @workspace/api-spec codegen, regenerating react-query hooks
  (useGetAdminStats) and zod schemas.

Frontend (artifacts/teaboy-os/src/pages/admin.tsx)
- Wired useGetAdminStats in AdminPage (enabled only for admins).
- Extended DashboardSection with two trend cards (new users 7d w/
  delta vs previous 7d, active services with inactive count) and a
  small bar chart of sign-ups over the last 7 days.
- Added matching i18n keys (en/ar) under admin.dashboard.

Notes
- Avoided sending all users to the client for trend computation, as
  recommended in the task brief.
- Verified pnpm typecheck passes and the new endpoint returns 401 to
  unauthenticated callers.
