Ryan Malloy f218cd468b Add GPS, IMU, and barometer sensor suite to BLE bridge firmware
RYS352A GPS on UART2 (GPIO5/6) with PPS interrupt (GPIO7),
MPU-9250 IMU and BMP388 barometer on shared I2C bus (GPIO8/9).
Sensor data exposed via dedicated BLE service with binary
notify characteristics alongside the existing NUS serial bridge.
Sensors degrade gracefully if not wired.
