Pull request overview
Adds initial firmware support for the CW2015 LiPo fuel gauge (voltage + SOC) and updates power-sensor initialization/detection to accommodate it.
Changes:
- Add CW2015 battery gauge initialization and reading logic (gated by
HAS_CW2015). - Refactor/rename the MAX17048 “lipo” init path (
lipoInit()→max17048Init()), and updatePower::setup()ordering. - Update I2C scanning to differentiate devices sharing address
0x62(SCD4X vs CW2015) and add CW2015 to the scanned device enum.

This i2c chip returns the measured battery voltage and estimate percent charged. Gated behind HAS_CW2015 for now.
