vangel76andClaude Opus 5.5 c9b9bf3aae #800: MP2 audio in MP4 and MOV decodes instead of playing silent ...

Problem: MP4 and QuickTime name MPEG audio without its layer (ffmpeg
stores MP2 as `mp4a` + esds object type 0x6B), and we always made the
layer III decoder for it. symphonia's decoder reads only the layer it
was made for, so every MP2 frame was rejected and the track played as
silence; MOV's `.mp2` sample entry was not recognised at all.

Fix: the MPEG audio decoder for MP4 / MOV is made on the first packet,
for the layer its frame header names (ISO/IEC 11172-3 2.4.2.3);
`.mp2` maps to the MPEG audio codec like `.mp3`; the track is labelled
"MPEG Audio" for layers I/II, as Matroska's is. Decoded tracks now match
ffmpeg sample-exactly (edit list trims the 481-sample encoder delay).
