[FIX] website_event: restore the online magic country

Removed with commit aebe199d80, but independant of is_online

Restore partially the feature, order by physical event is no more easy to restore
since is_online field doesn't exists anymore to sort.

Can be done as a custo if really required.

closes odoo/odoo#54516
