- Implemented PacketLogScreen to display and filter BLE packet logs. - Added functionality to export logs as CSV and text files. - Introduced clipboard copy feature for hex data. - Implemented clear logs functionality with confirmation dialog. - Enhanced MeshCoreBleService to log TX and RX packets with descriptions. - Added BufferReader methods for reading unsigned and signed 16-bit integers (big-endian). - Updated CayenneLppParser to read values as big-endian. - Created MessageStorageService for persisting messages to local storage. - Enhanced map markers to display telemetry data including voltage, humidity, and pressure.
