Add bulk sensor operations API

Implemented comprehensive bulk operations for BLE sensor management to improve
efficiency when working with multiple sensors simultaneously.

Features Added:
- bulkDisconnect: Disconnect multiple sensors at once
- bulkReboot: Reboot multiple sensors sequentially
- bulkSetWiFi: Configure WiFi for multiple sensors with progress tracking

Implementation Details:
- Added BulkOperationResult and BulkWiFiResult types to track operation outcomes
- Implemented bulk operations in both RealBLEManager and MockBLEManager
- Exposed bulk operations through BLEContext for easy UI integration
- Sequential processing ensures reliable operation completion
- Progress callbacks for real-time UI updates during bulk operations

Testing:
- Added comprehensive test suite with 14 test cases
- Tests cover success scenarios, error handling, and edge cases
- All tests passing with appropriate timeout configurations
- Verified both individual and sequential bulk operations

Technical Notes:
- Bulk operations maintain device connection state consistency
- Error handling allows graceful continuation despite individual failures
- MockBLEManager includes realistic delays for testing
- Integration with existing BLE service architecture preserved
