Truth-in-UI cleanup: wire real dashboard data, fix delete/dialog gaps

Phase 1 of frontend_tasks.md - stop showing fabricated/broken UI:

- Dashboard now fetches real stats (projects, tasks, users, pending
  approvals, API keys, developer stats, pending reviews, admin
  activity) instead of hardcoded numbers. Added services/developer.ts
  and services/review.ts wrappers for previously-unused backend
  endpoints.
- Wired ActivityFeed into every project's Overview page in place of
  the "coming soon" placeholder.
- Registered the missing /projects/:id/technical-specs route (view
  and service already existed, just unreachable).
- Fixed AssetDeleteConfirmDialog's raw styled divs to use the shared
  Alert component and wired it into AssetBrowser, matching
  ShotBrowser's impact-summary + type-to-confirm safety pattern
  (asset deletion was previously less safe than shot deletion).
- Fixed a shared bug in both delete dialogs where the impact-summary
  section never rendered (watch on the open prop needed
  { immediate: true }).
- Replaced native confirm()/alert() with styled AlertDialog/Dialog in
  NoteItem, TaskAttachments, and UserMenu's keyboard-shortcuts item.
- Removed dead-end UI: Google OAuth stub buttons, UserMenu items
  pointing at non-existent routes, the /developer/docs dead link, and
  the no-op action button on the API Keys placeholder page.
- Removed leftover debug console logging across 8 files.

Added frontend_report.md (full audit) and frontend_tasks.md (phased
checklist) as the reference for this and future phases.
