fix(webapp): unbreak local typecheck + unit tests

- Restore local import of `stripBackgroundWorkerMetadataForStorage` in
  `createBackgroundWorker.server.ts`; the prior diff turned it into a bare
  re-export and the existing in-file usage broke typecheck.
- Drop the `defaultPrisma` fallback on `findOrCreateBackgroundWorker`;
  importing `~/db.server` in test runs triggered the singleton's lazy
  Prisma client to attempt a localhost:5432 connection and surface as an
  unhandled rejection on shutdown.
