refactor: remove CursorAccountCard component and related localization entries

- Deleted the CursorAccountCard.vue component, which handled user account login and status.
- Removed associated localization entries from catalog.json and various language files.
- Updated Home.vue to eliminate references to the removed component.
- Refactored clientApi.js to remove unused account-related API functions.
