"""fc3b: rename credential.kind -> credential_type, drop status, add last_verified

Revision ID: 0011
Revises: 0010
Create Date: 2026-05-20

Aligns the credential table with the GallerySubscriber wire-field names
so the existing browser extension can POST to FC unmodified. Greenfield —
no rows exist in production yet, so no data preservation logic is
needed; the rename uses ALTER COLUMN rather than copy-then-drop.
