The service statically imported the db.server-backed runStore singleton,
which dragged the Prisma client into otherwise-light test module graphs and
opened an eager connection to DATABASE_URL on import. The metadata service
test then threw an unhandled connection error whenever no database was
reachable at the configured address.
Make runStore a required constructor option, pass the singleton at the
production construction site, and inject a testcontainer-backed store in the
tests.
