When several stations share the cheapest price within the radius (within 0.01p), the alert registers a dynamic UNNotificationCategory with up to 4 action buttons (brand + distance, nearest first) and taps open directions to the chosen station. Shared FuelStore.tiedStations helper used by both the live geofence path and the Settings real-data test; 35 tests pass.
