Use personal org for personal clips instead of display_name

Personal clips now properly belong to the user's personal org:
- Uses ensure_personal_org() to get or create user's personal org
- All clips now have a proper org_id (no more None)
- Clip owner is the org's slug (personal-{user_id} for personal orgs)
