Refactor user admin storage

Add IsAdmin to the User struct and update InsertUser to take a User value directly, simplifying the call site.

Collapse the unused owner/admin split into a single admin flag. TinyBeans MOTHER and FATHER relationships now map directly to IsAdmin, and SQLite stores only is_admin for user permissions.
