Task #183: clickable dependency counts on admin Apps/Services/Users

Turned the inline dependency-count badges on each admin row into
focusable, keyboard-accessible buttons that open a drill-in modal
listing the actual rows behind the count.

Backend (artifacts/api-server/src/routes):
  - apps.ts: GET /admin/apps/:id/dependents/{groups,restrictions,opens}
  - services.ts: GET /admin/services/:id/dependents/orders
  - users.ts: GET /admin/users/:id/dependents/{notes,orders,conversations,messages}
  All paginated (limit default 50, max 200; offset) returning
  {items, totalCount, limit, offset, nextOffset}. Restrictions joins
  the role names that include each required permission.

OpenAPI:
  - Added 8 path operations + 16 schemas (Item + Page) and re-ran
    `pnpm --filter @workspace/api-spec run codegen`.

Frontend (artifacts/tx-os/src/pages/admin.tsx):
  - New DependencyDrillIn component reuses DrillInShell (Escape +
    backdrop close, RTL/LTR safe) and the existing LoadMoreSection
    pagination pattern from AppOpensDrillIn.
  - Each count part in Apps, Services, and Users panels is now a
    <button> with a unique data-testid (e.g. app-counts-groups-213,
    user-counts-messages-5) and an aria-label that reads
    "View {count}".
  - AdminPage owns dependencyTarget state for Apps/Services counts;
    UsersPanel owns its own (it already encapsulates user list).

Translations:
  - Added admin.dependents.* (titles, subtitles, empty/error/load
    labels, conversation/order/message helper strings, order status
    enum) to en.json and ar.json.

Verification: - tx-os typecheck clean; api-server has only the pre-existing
    executive-meetings.ts errors (untouched).
  - e2e tested via runTest: login as admin, opened Apps panel,
    drilled into groups + opens (Load more grew 50→100), drilled into
    Tea orders, drilled into user 5 conversations and messages,
    switched to Arabic/RTL and re-opened the Groups drill-in to
    confirm Arabic rendering with no raw i18n keys.
