fix: voice message display, playback, recording UI, audio settings

- messagelist: parse content_type from JSON when DB column is empty
- messagelist: recording indicator (red dot + timer + cancel button)
- messagedelegate: editorEvent for play/pause toggle + progress bar
- messagedelegate: VoicePlayState tracking with QTimer
- InputBar: proper recordingContext (mediaDir + channelId)
- DbManager: dbPath() for media directory resolution
- AudioRecorder: peakLevel() for mic level meter
- VoiceEncoder: codec quality presets (Low/Standard/High)
- audiodevicesettingspage: Default device option first
- audiodevicesettingspage: mic level meter + test microphone
- audiodevicesettingspage: test speaker button
- audiodevicesettingspage: codec preset combo (Low/Standard/High)
- mainwindow: load opus_codec_preset from ui_state on startup
