fix: clarify user removal behavior in UI messaging

- Updated "Delete User" to "Remove User" to better reflect soft delete behavior
- Changed dialog messaging to explain account is deactivated, not permanently deleted
- Added comment in hook explaining soft delete implementation
- Backend performs soft delete (sets IsActive=false) with additional safeguards
- Preserves data for audit purposes while preventing login
