Fix crash shutdown + IMU BLE toujours actif pour tests

Browse Source 
PS_Win_BLE : crash à la fermeture d'Unreal (assertion Index >= 0 dans
UObjectArray) car RemoveFromRoot() était appelé dans ShutdownModule()
alors que l'UObject array est déjà partiellement détruit. Fix : cleanup
du BLEManager déplacé dans un delegate FCoreDelegates::OnPreExit qui
s'exécute plus tôt, avant la destruction des UObjects.

uproject : désactivation explicite de WinBluetoothLE (les nœuds
Blueprint restaient dans le groupe Bluetooth Low Energy car le plugin
était chargé automatiquement depuis le dossier Plugins/).

Firmware : envoi IMU BLE découplé du debug mode pour pouvoir tester
la caractéristique 6E400002 à distance (TODO_TEST — remettre la
condition debugMode != DEBUG_OFF quand Pico Motion Tracker intégré).
