Aonsoku BasicAuth v0.14.0-ba.2

Aonsoku BasicAuth v0.14.0-ba.2

Changes:

• Carries upstream development playback fallback from victoralvesf#389.
• Requests server-side opus transcoding for .m4a streams so ALAC containers can play through Chromium/Electron.
• Uses song metadata duration when a transcoded stream reports infinite duration.
• Tightens player component coverage for .m4a stream URLs, infinite-duration fallback, and repeat-all vs repeat-one loop behavior.

Notes:

• Reviewed victoralvesf#366, but this release does not claim to fix that issue. The native audio element still drives track-end advancement; proving victoralvesf#366 needs a reproducible stream/media case.
• This fork remains scoped to reverse-proxy BasicAuth support. General Aonsoku issues are out of scope here unless they directly affect this fork's BasicAuth patch or are deliberately carried as narrow upstream-development fixes.
