Alerts choose their own fuel, independent of the Stations tab
The proximity monitor was tied to the Stations-tab fuel selection, so switching the list to another fuel silently re-targeted geofences. Now the Alerts tab has its own 'Fuel to monitor' picker (persisted as fuelboard.alertsFuel): - Monitor reads loadAlertsFuel() on init/background relaunch - Changing the alerts fuel re-registers geofences around stations selling that fuel only - Favourites priority slots stay scoped to the monitored fuel - Tests: alerts fuel round-trip + default (33/33 passing)
