refactor(db): port service clone/move ops to sqlc (#76)

Tranche 2: cloneServiceRow's INSERT...SELECT (volumes and traefik_labels
now read straight from the source row — traefik_labels was silently
dropped before, and the jsonb param round-trip goes away), domain and
variable copies, name-conflict counts, move UPDATE, project owner check.
Also fixes serviceWriteAccess: user_id is a context string, not a
uuid.UUID — the tranche-1 cast silently failed owner checks for
non-admins. Live tests cover the domain invariants and a full clone
round-trip (config, domains, variables).
