Function get_active_by_id 

pub async fn get_active_by_id(
    conn: &mut PgConnection,
    id: Uuid,
) -> ModelResult<User>

Like get_by_id, but only returns a user that is not soft-deleted.

A soft-deleted (banned/removed) user yields RecordNotFound, the same as a nonexistent id, so callers that must reject deleted accounts can treat both cases identically. get_by_id deliberately does not filter, since some callers fetch a user’s own deleted row.
