bug: component init errors ignored in main.cpp

[gdellis]

Problem

GPS, LoRa, Accelerometer, and BLE init() return values are ignored in main.cpp:39-53. Only BatteryDriver::init() has error handling. If any critical component fails to initialize, the system runs in a broken state undetected.

Location

• firmware/main/main.cpp:39-53

Severity

HIGH - System operates in broken state without warning

Suggested Fix

Add error checking for all component init() calls and transition to ERROR state if critical components fail.

[gdellis]

Fixed in PR #55 - component init errors now handled with ESP_ERROR_CHECK for critical components (LoRa, BLE) and error logging for others (GPS, accelerometer, battery).
