Deluan Quintão 664217f3f7 fix(transcoding): play WAV files directly in browsers instead of transcoding (#5309)
* fix: allow WAV direct play by aliasing pcm and wav codecs

WAV files were being transcoded to FLAC even when the browser declared
native WAV support. The backend normalizes ffprobe's pcm_s16le (and
similar PCM variants) to the internal codec name "pcm", while browsers
advertise WAV support as audioCodecs:["wav"] in their client profile.
The direct-play codec check compared these literally and rejected the
match with "audio codec not supported", forcing a needless FLAC
transcode.

Added {"pcm", "wav"} to codecAliasGroups so the matcher treats them
as equivalent. The container check runs first, so AIFF files (which also
normalize to codec "pcm" but use container "aiff") cannot
accidentally match a WAV direct-play profile.

* feat: include profile details in direct-play rejection reasons

The transcodeReason array returned by getTranscodeDecision previously
contained one generic string per failed DirectPlayProfile (e.g., five
copies of "container not supported"), making it hard to correlate a
reason with the profile that rejected the stream.

Each rejection reason now embeds the offending source value (in single
quotes) along with a compact representation of the full profile that
rejected it, rendered as [container/codec]. For example, clients with
two distinct ogg-container profiles (opus and vorbis) produced two
identical rejection strings; they now read "container 'wav' not
supported by profile [ogg/opus]" and "container 'wav' not supported
by profile [ogg/vorbis]", making each entry in the transcodeReason
array unique and self-describing.

A small describeProfile helper renders profiles as [container/codec]
(or [container] when no codec is constrained).

* refactor(stream): address code review — narrow pcm/wav match, tighten tests

Responds to reviewer feedback on the initial PR:

- Replace the symmetric pcm↔wav codec alias with a contextual
  isPCMInWAVMatch check in checkDirectPlayProfile. The alias
  unconditionally equated the two names in matchesCodec, which would
  let AIFF sources (also normalized to codec "pcm") falsely satisfy
  a codec-only ["wav"] direct-play profile that omitted containers.
  The new check additionally requires src.Container == "wav" before
  bridging the names, closing the false-positive path.

- Tighten the rejection-reason test assertions to verify the new
  formatted output (source value + profile descriptor) instead of
  just matching loose substrings like "container", preventing
  unrelated rejections from satisfying the expectations.

- Add coverage for the WAV→wav-codec acceptance path and for the
  AIFF-in-wav-codec-profile rejection path to pin down the contract
  of isPCMInWAVMatch.

* refactor(codec): rename isPCMInWAVMatch to matchesPCMWAVBridge for clarity
