[web] avoid UserAnalyticsIdCache (#33121)

* [web] always provide an analyticsId when registering new users

* [web] add recordEventForMongoUser and use it during login

* [web] use recordEventForMongoUser/recordEventForSession where possible

* [web] use session cache for analyticsId when refreshing features

* [web] add setUserPropertyForMongoUser and use it where possible

* [web] use setUserPropertyForSessionInBackground where possible

* [web] use mongo user for analyticsId when setting utm user properties

* [web] admin-panel: user updated user when sending events

* [web] enforce labsProgram being populated on user object

* [web] revert FeaturesUpdater.refreshFeatures change

* [web] labs: move session maintenance into handler

* [web] analyticsMiddleware: ensure that all users have labsProgram field

* [web] migrate a few more events to recordEventForSession

* [migrations] mark back-fill of db.users.analyticsId as required

* [web] setUserPropertyForSessionInBackground: throw early
