feat(i18n): update session management translations and improve provider configuration handling

- Updated English and Chinese translations for session management, including "Unified Message Origin" and "Follow Config".
- Enhanced provider configuration options to include "Follow Config" as a selectable item.
- Removed unused clear buttons and refactored provider configuration saving logic to handle updates and deletions more efficiently.
