refactor: update PAM session status handling and improve enum definitions

- Changed PAM session status from 'Expired' to 'Ended' in the database update logic and service layer for clarity.
- Updated the PamSessionStatus enum to consolidate the definitions of 'Ended' and 'Expired', reflecting that 'Ended' can result from both user action and automatic expiration.
- Removed references to 'Expired' in the frontend components and adjusted related UI elements for consistency.
