 fd433c220e [BLE] Add BM6 Battery Monitor connection support (#2274) 
* [BLE] Add BM6 Battery Monitor connection support

Implement BLE connection support for BM6 Battery Monitor devices,
following the BM2 pattern with BM6-specific protocol handling.

Key features:
- Encrypted command/response using AES-128 CBC
- Read voltage, temperature, and State of Charge (SoC)
- Home Assistant MQTT Discovery support
- Device tracker integration

Technical implementation:
- Add BM6_connect class with encrypted command handling
- Encryption key (static const): "leagend\xff\xfe0100009"
- Parse hex string positions for voltage (15-17), temp (8-9), SoC (12-13)
- Add discovery with 3 sensors (voltage, temperature, battery %)
- Validate message signature (D15507)
- Add canWrite() check before writing to characteristic
- Empty stub for non-ESP32 builds

Code quality improvements:
- Extract AES key as static constant to avoid duplication
- Use shared jsonVoltBM template for both BM2 and BM6
- Clean up commented-out reasoning in parsing logic

Based on reverse engineering from:
https://github.com/JeffWDH/bm6-battery-monitor

Files modified:
- main/gatewayBLEConnect.h: Add BM6_connect class
- main/gatewayBLEConnect.cpp: Implement BM6 connection logic
- main/gatewayBT.cpp: Add detection, connection, and discovery handlers
- main/config_mqttDiscovery.h: Rename jsonVoltBM2 to jsonVoltBM
