Add deploy/RUNBOOK.md: the operator procedure to rebuild the API
deployment end to end (image build, compose and the nestquest-db
volume, Traefik TLS and routing on nukapi-03, Authentik OIDC, secrets,
network separation, Litestream backup), restore the database from the
SFTP replica, and verify the result. Point api/README.md at it.
The restore steps were rehearsed locally against a file replica using
the committed compose file.
