Notifications for chargers

e.g. if there is a new fault report for one of your favorite chargers, or when a charger becomes available/unavailable

Would require a background task to regularly check for updates. In the former case, the background task should run always, but at low intervals (maybe once a day) to save battery and data. In the latter case, the background task should run at a higher frequency (maybe every 5-10 minutes), but only for a specified amount of time.

Possible extension: In the notification that a selected charger becomes unavailable, directly suggest nearby alternatives.
