Added optional FFmpeg profiles: recommended M4A/AAC-LC or requested MP4/H.264 + AAC. Added MIME-aware, playsinline audio playback. Added dashboard controls under Plans & Platform → Voice Transcoding / FFmpeg. Added Apache/Nginx media MIME configuration and documentation. Core implementation: voice_transcoder.php (line 72), messages.php (line 86), and cyberchat-app.js (line 635).
