The three planner view switches lived in sessionStorage only, so a new tab,
another browser or another device opened every trip on the plain view again.
They are now kept per trip in one user setting, planner_trip_views, validated
against a contract in @trek/shared. The server keeps only switches that are on
and only trips the user can still open, so a deleted trip or one the user left
drops out on the next write. The tab copy in sessionStorage stays and answers
until the settings have loaded.

The day route toggle and its travel profile, the whole-trip overview, the
map lock, the recorded Dawarich trail, the fit key and the effect that
fits each trip once move out of useTripPlanner into usePlannerMapView.
A new test calls every toggle and the automatic route, which no test
reached before.
useTripPlanner calls the hook where that code used to sit, so the
Dawarich fetch and the first fit still run in the same order and the
planner returns the same object. handleSelectDay now lists the map lock
ref, the phone ref and setFitKey it receives from the hook; they never
change identity, so nothing behaves differently.
