[FIX] event: ensure event_registrations_open can always be computed

Using a compute_sudo ensure this field is correctly computed (aka without
crash) if someone is allowed to read the event but not all its sub models.
For example event_registrations_open reads the active flag of a product
linked to a ticker which may not be readable by public users. This field
is used in frontend templates and therefore usable by external people.

Also remove unnecessary registrable rendering parameter in website_event
as it has been replaced by computed fields.
