feat(ui): render the location tray's pills, mini status and search error from a store

LocationControls (./ui/location) no longer builds the city and landmark
pills or writes the mini status and the search error: it presents the tray
and hands it to its publish option, so the entry stays Vue-free. The shell
publishes it to a new gev-location store and connects the controls, and
the dock renders it and calls chooseCity() and choosePoi(). The landmark
row still expands a frame after its pills render. The search field, its
toggle and the reset buttons keep their listeners. The location QA harness
reads the rendered elements.
