The Jobs screen only displayed an asset name when the enqueueing code
stuffed assetName into the BullMQ job data. YouTube imports did that;
upload-triggered proxy/thumbnail jobs didn't — so everything except
YouTube showed em dashes in the Asset column.
Fix it centrally: after we collect jobs from BullMQ, look up names
in one bulk SELECT against the assets table for any job that has an
assetId but no asset_name. Applies to /jobs, /jobs/:id, and the SSE
events stream. Lookup failures fall through silently rather than
500-ing the whole list.
