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
