Remove verification related feature flags (#4345)

- `:verification` flag is no longer needed,
   however we'll keep the old "awaiting first pageview" flow
   for Community Edition where verification is not available
   by default
 - `:traffic_drop_notifications` have been tested and should
   be enabled for everyone
