- Fix use-after-free crash on hangup: set _call_state=IDLE before deleting
_lxst_audio, preventing pump_call_tx() (runs without LVGL lock) from
accessing freed memory
- Replace single-slot _call_signal_pending with 8-element ring buffer queue
to prevent signal loss when CONNECTING+ESTABLISHED arrive in rapid succession
- Extract TX pump into pump_call_tx() called right after reticulum->loop()
for low-latency audio TX without LVGL lock dependency (was buried at step 10)
- Tune ES7210 mic gain to 21dB (was 15dB) to improve Codec2 input level
without ADC clipping that occurred at 24dB
- I2S capture: use APLL for accurate 8kHz clock, direct 8kHz sampling
(no more 16→8kHz decimation), DMA 16x64 for encode burst headroom
- Reduce Reticulum log verbosity to LOG_INFO (was LOG_TRACE)
- BLE: add ble_hs_sched_reset() tiered recovery before reboot on desync,
widen supervision timeout to 4.0s for WiFi coexistence
- Add UDP multicast log broadcasting and OTA flash support

Replace custom ES7210 register-level driver with the verbatim LilyGO
T-Deck Plus ES7210 library. The custom driver was writing MODE_CONFIG
and clock doubler registers (master mode path) which broke the ES7210's
clock chain, causing all-zero PCM output. The LilyGO library in slave
mode leaves those registers at power-on defaults, which is correct since
the ESP32 I2S master provides MCLK/BCLK/LRCK.
Also includes LXST voice call protocol improvements:
- LXST IN destination for receiving calls
- Announce handler for tracking voice-capable peers
- Path request before outgoing calls
- Throttled SPIFFS saves in microReticulum (dirty flag)
