feat(all): transcoding improvements (#2171)

* test: rename some fixtures and add text for vertical video conversion

* feat: transcode video asset when audio or container don't match target

* chore: add niceness to the ffmpeg command to allow other processes to be prioritised

* chore: change video conversion queue to one concurrency

* feat: add transcode disabled preset to completely turn off transcoding

* linter

* Change log level and remove unused await

* opps forgot to save

* better logging
