rlcd: fix audio freeze, OOM, robot sound, pops and voice recorder

- Fix DTS I2S pinmap to RLCD correct pins (mclk 16, bclk 9, ws 45, tx 8, rx 10) resolving GPIO5 conflict with display DC
- Port ES8311 DAC and ES7210 mic ADC init from working MicroPython audio_util.py
- Fix I2S DMA OOM by reducing to 6x160 and RX fallback to TX-only
- Fix MCLK multiple for 12.288MHz family (16k->768 exact) to avoid robot sound
- Avoid ES8311 reclock glitch for 16k rate to eliminate pop
- Clean log spam (file lock once, listDir DEBUG, I2S DEBUG) that caused UART jitter
- VoiceRecorder: request stereo from ES7210 and downmix left channel to fix mic-like low pitch
