feat: introduce FixMate Flutter app and React dashboard

- Add Flutter app shell (FixMateApp/MainScreen) with tabs: Report, Map,
  My Reports, Settings
- Implement capture and review flow (image_picker, geolocator, deterministic
  mock AI), and local storage (SharedPreferences + photo files on mobile)
- Build Map screen with flutter_map, marker clustering, filters, legend,
  marker details, and external maps deeplink
- Add My Reports list (view details, cycle status, delete) and Settings
  (language toggle via Provider, diagnostics, clear all data)
- Introduce JSON i18n loader and LocaleProvider; add EN/BM assets
- Define models (Report, enums) and UI badges (severity, status)

- Add static React dashboard (Leaflet map with clustering, heatmap toggle,
  filters incl. date range, queue, detail drawer), i18n (EN/BM), and
  demo data

- Update build/config and platform setup:
  - Extend pubspec with required packages and register i18n assets
  - Android: add CAMERA and location permissions; pin NDK version
  - iOS: add usage descriptions for camera, photo library, location
  - Gradle properties tuned for Windows/UNC stability
  - Register desktop plugins (Linux/macOS/Windows)
  - .gitignore: ignore .kilocode
  - Overhaul README and replace sample widget test
