refactor: PollFuelPricesJob calls service directly

Audit item #11. The job was a one-line Artisan::call wrapper around
fuel:poll --full. Routing through Artisan adds output buffering and
swallows typed exceptions before they reach the queue's failed-job
handler. Now injects FuelPriceService and replicates the --full path
(refreshStations + pollPrices + PricesUpdatedEvent) directly.
