Fix issue #5025: Log the session ID in addition to the runtime ID

[openhands-agent]

This pull request fixes #5025.

The PR successfully implemented the requested changes to log both runtime ID and session ID in the chat interface. Specifically:

1. The chat interface frontend was updated to display and log both IDs by:

   • Adding sid to the data being received from the backend
   • Implementing console logging for both runtime ID and session ID
   • Adding visual styling to distinguish between the two IDs

2. The backend endpoint /api/remote-runtime-config was modified to include the session ID in its response, accessing it through request.state.sid

The solution covers both the frontend and backend changes needed to fully implement the requested functionality, making it a complete fix for the issue. The changes appear clean and maintain the existing codebase structure while adding the new functionality.

This PR can be confidently passed to a human reviewer as it directly addresses the issue requirements and includes appropriate changes on both ends of the application.
