Myron Blair b74d8a2652 Add fast audio-only transcode mode; fixes no-sound from AC3/DTS/EAC3
Root cause of "movies have no volume control / can't hear anything":
0 of 200 movies had finished transcoding, so every movie streamed its
raw source file — and BDRip/AVI sources very commonly carry AC3/DTS/EAC3
audio, which no browser can decode natively. Browsers respond by hiding
the volume control entirely when they can't find a playable audio track,
which is exactly the symptom reported.

New "audio" transcode quality: video is stream-copied untouched, only
the audio track is re-encoded to AAC — dramatically faster than a full
ABR pass since no video re-encoding happens. Added:
- transcode_audio_fix() in transcode.py
- "audio" as a valid quality value everywhere quick/abr were validated
- POST /transcode/queue/fix-audio-all: cancels every still-pending job
  and replaces it with the fast audio fix for the same content (running
  jobs are left alone), so a library-wide backlog of slow ABR jobs can
  be swapped for something that actually restores sound soon
- Per-movie "Audio" button in Admin, "Fix Audio (Fast, All)" button on
  the Transcode Queue page

Note: this doesn't help HEVC/x265 sources, whose video (not just audio)
isn't natively browser-playable either — those still need a full ABR
re-encode to H.264.
