refactor: rename bruno/auth folder to bruno/user

The auth folder now contains user management endpoints beyond just authentication:
- User registration/login (auth)
- Profile management (user)
- Theme settings (user preferences)
- Ebook folder management (user settings)

Renaming to 'user' better reflects the expanded scope covering user accounts, preferences, and settings management.
