Ten migration-critical modules become mesh-buildable (issue 060)

keycloak, mailu, minio, mongodb, mssql, nextcloud, portainer, redis,
umami and verdaccio get the Dockerfile + build section the eight
buildable modules already had; their runtime containers name the
artifact instead of a placeholder digest.

One convention, settled (060's open question, informed by 061): the
runtime container runs serve mode with every serve-time entrypoint in
MESH_TOOL_MODULES — tools serve, events flow, and a provider's
provisioner reconciles in the same process with the broker connected.
postgres, gitea and lavinmq are retrofitted from args-run provisioners,
which served no tools and emitted lifecycle events nowhere.

route-proxy is deferred: its build context is the mesh-controller
repository, a cross-repo shape the build section cannot yet express.
