refactor: simplify user profile to username-only state

Removed the full user profile API endpoint and state management in favor
of a simpler username-only approach. The previous IUserProfile interface
contained both email and username, but only username was actively used
throughout the application.

Changes:
- Backend: removed /api/userprofile endpoint and userProfileApi service
- Frontend: renamed User/Profile store slice to User/Name
- API: removed IUserProfile interface from common DTO
- Simplified API response to return username string directly
- Updated all imports and selectors to use new username-only state
- Renamed actionCreators from userProfileActionCreators to usernameActionCreators
- Updated all tests to reflect new naming and structure

This reduces complexity and aligns the state structure with actual usage.
