Ryan Brown 8439d9bbb6 Fix late background alerts and cache starvation
- Increase background refresh threshold: Raised the edge distance check in GpsController from 1000m to 2500m to guarantee new Overpass data is fetched well before the user drives out of the cached bounding box.

- Fix bounding box race condition: Added await to the background fetch handler in MapView so tracking bounds only shift forward after the network request successfully finishes.

- Make debounced fetches awaitable: Refactored fetchAndUpdate in NodeProviderWithCache to return a Future<void> using a Completer, bridging the 400ms debounce timer.

- Prevent hanging futures: Added state checks for _activeCompleter to instantly resolve canceled network requests during rapid map panning, preventing fatal StateError crashes and infinite UI hangs.
