Implement BLE connection state machine

Browse Source 
Add comprehensive connection state management to BLE Manager with:
- Connection state enum (DISCONNECTED, CONNECTING, CONNECTED, DISCOVERING, READY, DISCONNECTING, ERROR)
- State tracking for all devices with connection metadata
- Event emission system for state changes and connection events
- Event listeners for monitoring connection lifecycle
- Updated both RealBLEManager and MockBLEManager implementations
- Added test suite for state machine functionality
- Updated jest.setup.js with BLE mocks
