Add member transfer configuration and UI enhancements

Introduced MemberTransferConfig model and integrated it into the backend, allowing for the storage and retrieval of member transfer settings. Updated server routes to include member transfer configuration endpoints. Enhanced the frontend with a new MemberTransferDialog component for user interaction, added a dedicated route for member transfer settings, and updated the App.vue to include a link for accessing these settings. Improved the loading state and configuration handling in the dialog for better user experience.
