Implement comprehensive BLE cleanup functionality that properly
disconnects all devices and releases resources when user logs out.
Changes:
- Add cleanup() method to BLEManager and MockBLEManager
- Update IBLEManager interface to include cleanup
- Add cleanupBLE() to BLEContext to disconnect all devices
- Implement callback mechanism in api.ts for BLE cleanup on logout
- Wire up BLE cleanup in app layout to trigger on logout
- Add unit tests for BLE cleanup functionality
This ensures no BLE connections remain active after logout,
preventing resource leaks and potential connection issues.
