For authenticated users, save the user consent status to key-value store

Problem/Motivation

For authenticated users the consent status (or cookie value of COOKiES cookie) should be saved to the DB-store. So if auth user visit the site with another browser (or using a safe (incognito) browser, that clears all cookies, activities and caches by default) they don't have to re-evaluate their decisions.

Proposed resolution

• Use callback function from cookiesjsr for an action-handler, that saves the user decision to the key-value store.
• Hook up when user logs in, if cookie 'cookiesjsr' for user:xy is stored.
• -> IF FALSE: do nothing.
• -> IF TRUE: Look up if cookie 'cookiesjsr' was already set in anonymos state.
• ---> IF TRUE: Update store with current state.
• ---> IF FALSE: Set cookie 'cookiesjsr' with recent evalution state from store.
