perf(webapp): select only needed columns in dev current-worker lookup

The DEVELOPMENT branch of findCurrentWorkerFromEnvironment fetched every
BackgroundWorker column (including the large metadata JSON) but the function
only returns 7 small fields. Add a select matching the declared return type so
the discarded columns never leave the database.
