feat: ship DDFM v2 (postal-code OR-rule) via the award catalog so it reaches the team

DDFM now derives the French department from the address postal code, not only
from a note typed by hand — the catalog def gains the address OR-rule (\d{2}\d{3}
-> Dxx), France+Corsica scope, and version 2. On next launch every operator whose
DDFM is unedited auto-upgrades to it (user-edited copies are offered it); the
materialised award_refs then recompute so ~500+ French QSOs gain their department.

Also: a catalog definition update now clears the award_refs backfill flag, so any
future catalog bump self-heals the stored columns without a manual flag bump.
