Derive consent mode from geolocation, not banner config

The consent mode is now determined dynamically by the visitor's
country and its applicable regulation. The configured consent_mode
column is dropped from cookie_banners and added to
cookie_consent_records to persist the geo-derived mode at
consent-recording time. When no regulation matches, the default
is OPT_OUT.
