fix(worker): conform — write ProRes/DNxHR to MOV, not MP4

Browse source 
The final concat-demux + encode step erred with:
  [mp4] Could not find tag for codec prores in stream #0,
        codec not currently supported in container
  [out#0/mp4] Could not write header (incorrect codec parameters ?)

ProRes and DNxHR live in QuickTime (.mov), not MP4. The output path,
S3 key, and asset-row filename were all hardcoded to .mp4.

Pick the container from the codec:
  prores / prores_hq / prores_4444 / dnxhr_hq → mov
  h264 / h265 / anything else                 → mp4

outputExt is computed once at the top of the worker (before tmpfile
creation) and reused for the temp output, the S3 key
(jobs/<id>/conformed.<ext>), and the assets row's filename column.
