Consent Mode does not update in place after the consent choice GCM_008

Affected: broken

Call gtag('consent', 'update') immediately after the visitor's choice, with the correct values for both accept and reject. Do not rely on a page reload: it creates duplicate pageviews and breaks session attribution.

Warning
Consent state was not updated after the banner choice GCM_003

Make both the accept and the reject button update the consent state through the GTM Consent API or gtag('consent', 'update').
