Add Android support with configurable server URL and location permissions
- Add shared_preferences for persisting server URL - Add SettingsService and PlatformService - Add server URL input field on non-web platforms - Make ApiConfig baseUrl configurable at runtime - Add Android location permissions (ACCESS_FINE/COURSE_LOCATION, INTERNET) - Request location permission on login and map init - Fix geo_id type: use String instead of int (UUID format) - Align share_service with API spec: remove unique_id, use share_id only - Fix watch endpoint response: last_update instead of created_at - Add error handling with SnackBars for geo operations - Wrap login screen in SingleChildScrollView for keyboard handling - Update map tile layer with userAgentPackageName for OSM
