BIG FIX: Provisioners were calling centralManager.connect() but
BLEManager is the CBCentralManagerDelegate — provisioners never
received didConnect/didFailToConnect callbacks, so connections
ALWAYS timed out after 5s regardless. This is why provisioning
kept failing. Fixed by:
1. Adding didConnect/didFailToConnect/didDisconnect to BLEManager
2. Provisioners register connection callbacks via bleManager
3. Increased connection timeout from 5s to 10s
DIAGNOSTICS: Added ProvisionLog system so failures show a timestamped
step-by-step log of what happened (with Share button). Every phase
is logged: init, API calls, connect attempts, service discovery,
auth, write commands, and errors.
