Rather than requiring an operator to create a GPG key and a K8s secret, the
registry now provisions itself: on first start artifactapi generates a signing
keypair and persists it in a new signing_keys table, so all replicas share one
key and there is nothing to set up. TF_SIGNING_KEY_PATH still overrides with a
bring-your-own key when set.
- signing_keys table + GetSigningKey / InsertSigningKeyIfAbsent (ON CONFLICT DO
NOTHING so a replica race converges on one key)
- tfsign.Generate, LoadArmored, and LoadOrCreate(store, purpose)
- server prefers a configured key file, else LoadOrCreate against the DB
- tests: generate/load round-trip, load-or-create generates once then reuses,
DB insert idempotency
