feat: add delete session functionality with confirmation dialog

- Introduced a new DeleteSessionDialog component for confirming session deletions.
- Integrated the delete session dialog into the SessionManager component, allowing users to delete sessions with a confirmation prompt.
- Updated the UI to handle session deletion more intuitively, enhancing user experience.
- Refactored existing delete confirmation logic to utilize the new DeleteConfirmDialog component for consistency across the application.
