Adriano b9f43a0ede Stazioni: camera_url e camera_source, GET /api/stations/by-code/{code} (#72)
Migrazione 020 con le due colonne su stations, campi in modello, schemi e
servizio (validatore http(s) come vision_worker_url), nuova route by-code
dichiarata prima di /{station_id}. Test di migrazione su e giu e di API.

"""Station and StationRecipeAssignment models.
A Station represents a physical control point (typically one per tablet/PC).
Recipes are assigned to stations so that each station only sees the products
it is supposed to inspect.
