feat(chat): Enhance session management with new API endpoints and filtering options

- Added `status` query parameter to `list_sessions_api` for filtering sessions by their status (active/closed).
- Introduced `close_all_sessions_api` endpoint to allow users to close all active sessions for the current actor.
- Updated `SessionRepository` to support status filtering in session listing and implemented logic for closing active sessions.
- Improved Redis connection settings for better performance and reliability.

This update enhances the chat functionality by providing more control over session management, improving user experience and system efficiency.
