fix: handle EntityMetadataNotFoundError as a GraphQL NotFoundError

When a workspace object's TypeORM entity metadata is not found (e.g., due
to cache desync after creating/deleting custom objects), the raw TypeORM
EntityMetadataNotFoundError was propagating unhandled through the GraphQL
resolver, causing a 500 error reported to Sentry.

This adds handling for EntityMetadataNotFoundError in the workspace query
runner exception handler, converting it to a proper GraphQL NOT_FOUND
error that is returned gracefully to the client.
