Fix BLE NullPointerException crash on Android

Root cause: react-native-ble-plx v3.5.0 calls Promise.reject(null, ...)
in 17 places in BlePlxModule.java, causing NullPointerException when
BLE operations fail (e.g., device disconnect during WiFi config).

Fixes applied:
- patch-package: Replace all safePromise.reject(null, ...) with
  safePromise.reject(error.errorCode.name(), ...) in native Java code
- Lazy BLE initialization: Defer BleManager creation until first use
- Safe error handling: Add transactionId and safeReject wrapper
