Merge branch 'main' into feature/user-auth

Resolved merge conflicts integrating PR #13 (Home Page with MUI v2):

Backend changes:
- settings.py: Combined INSTALLED_APPS (accounts + jobs + corsheaders),
  kept HEAD's REST_FRAMEWORK (AllowAny + throttling) and SIMPLE_JWT,
  added origin/main's CORS config
- urls.py: Combined admin/, api/auth/, api/ routes
- pyproject.toml: Combined all dependencies (simplejwt + cors-headers)
- uv.lock: Regenerated with updated dependencies

Frontend changes:
- package.json: Combined all deps (axios + MUI + emotion)
- App.tsx: Integrated AuthProvider with MUI AppLayout, all routes
- HomePage.tsx: Show landing view when unauthenticated, MUI dashboard
  when authenticated
- main.tsx, tsconfig.json, vite-env.d.ts: Combined both versions
- yarn.lock: Kept origin/main's version (regenerated on install)
