feat: Enhance SSE session management and agent status display

- Implemented session ID binding from ASGI HTTP scope and request context to improve SSE connection tracking.
- Added functions to mark SSE sessions as connected or disconnected, and to check if an agent is connected via SSE.
- Updated agent status display in the UI to include transport type and last seen time for offline agents.
- Refactored agent tooltip to show detailed status information, including state and transport type.
- Improved CSS styles for agent status items and tooltips for better user experience.
- Added new debug logging for active SSE sessions and connection agents.
- Introduced a new script for querying agent and thread information from the database.
