* fix(media): recognize MP3 and M4A as voice-compatible audio Telegram sendVoice supports OGG/Opus, MP3, and M4A, but isVoiceCompatibleAudio only recognized OGG/Opus formats. - Add MP3 and M4A extensions and MIME types - Use explicit MIME set instead of substring matching - Handle MIME parameters (e.g. 'audio/ogg; codecs=opus') - Add test coverage for all supported and unsupported formats * fix: narrow MIME allowlist per review feedback Remove audio/mp4 and audio/aac from voice MIME types — too broad. Keep only M4A-specific types (audio/x-m4a, audio/m4a). Add audio/mp4 and audio/aac as negative test cases. * fix: align voice compatibility and channel coverage (#15438) (thanks @azade-c) --------- Co-authored-by: Peter Steinberger <steipete@gmail.com>
