CI: Fix API jobs — drop container override, replace bitnami/minio

Gitea Actions execs JavaScript actions (actions/checkout) inside the
job container, unlike GitHub Actions which uses the host. The uv Python
image has no Node.js, causing exit 127. Fix: drop container: from all
three API jobs and run on the default ubuntu-latest environment.

Integration tests: Postgres stays as a service container (no special
startup command needed). MinIO moved to a manual docker run step using
quay.io/minio/minio with `server /data` — the only way to pass a
startup command. Bucket created via mc binary downloaded in-step.
Service hostnames change from service-name to localhost now that there
is no explicit job container.
