Add complete custom fields implementation and entry editing

- Add custom field CRUD in admin UI (create, read, update, delete)
- Display custom fields on frontend form with proper field types
- Save custom field values on form submission
- Display custom field columns in entries table (admin and public)
- Include custom field values in all export formats (CSV, PairGoTh, OpenGotha, McMahon)
- Add Edit button and form for entries
- Update entry handler to support editing with custom field values
- Add success/error notices for all admin actions
