SMA-2 round 2: keep the driver keys out of the schema, translations and labels

Owner decision 2026-11-07: clients see nothing new until SMA-4. config.yaml,
translations, labels and the page layout are back to 23ff9d0's. The validation
of the keys stays for callers that skip the schema.

     yet: a later driver's entry must not be refused for carrying them.
