Point the e2e add flows at whichever add control a surface shows

A list that is empty now carries its add action in the empty state
instead of the header, and on the phone shell the dashboard's add opens
the capture sheet. The overflow, mood timestamp, measurement flow,
onboarding tour and delegated-write journeys accept either control; the
measurement list's empty-state add gets a stable data-slot for that.
