refactor(db): port runtime ops to sqlc

Tranche 5 — all 24 raw sites in runtime.go. Adds runtime.sql with the
legacy-column COALESCE loader (type/image/command/git_repo fall back to
service_type/image_name/start_command/source_url), env-var reads,
sibling refs, deployed-image concat, and conditional published-port /
replica writes. Status transitions reuse SetServiceStatus.

loadReadableService now shares GetServiceRuntimeWithOwner — the projects
join is safe (FK) and drops a duplicated 24-column select.

TestRuntimeLiveInvariants verifies the COALESCE chain against a service
seeded with only legacy columns, plus refs, port, variables, agent
listing, image concat, and conditional updates on live Postgres.
