Adds Ingest → YouTube. UI takes a URL + project, API enqueues a BullMQ
"import" job, worker shells out to yt-dlp, lands the MP4 in S3 at the
same originals/{assetId}/... path uploads use, then hands off to the
existing proxy queue. Imported assets share one lifecycle with uploads
from that point on.
Worker container picks up yt-dlp + python3 (apk on alpine, apt on the
GPU variant). The new 'import' queue is registered in jobs.js so it
appears in the Jobs SSE stream and retry/delete work for free.
