feat(logging): implement client log streaming and management

- Added log streaming functionality for clients, allowing real-time log access via SSE.
- Introduced LogHandler to manage log streaming requests and responses.
- Implemented LogSessionManager to handle active log sessions and listeners.
- Enhanced protocol with log-related message types and structures.
- Created Logger for client-side logging, supporting various log levels and file output.
- Developed LogViewer component for the web interface to display and filter logs.
- Updated API to support log stream creation and management.
- Added support for querying logs by level and searching through log messages.
