Replace proprietary flutter_background_geolocation (requires paid license
for Android release builds) with free flutter_foreground_task package.
Background location tracking now uses foreground service with periodic
geolocation updates every 30 seconds.
Add flutter_background_geolocation for background location tracking on Android.
Service automatically sends coordinates to server when app is in background.
Error messages are shown as system notifications using flutter_local_notifications.
