fix(ui): point import controls inward and give Google Maps its own mark

Every import button in the client wore an outgoing arrow, so the control that
pulls a booking or a place list in looked like it was about to send something
out. The places-import sheet managed to contradict itself inside one screen:
Download in the header, Upload on the row below it, Upload again on the file
step. Imports now take Download, or FileDown where the button opens a file
picker; genuine uploads and the desktop drop zones keep Upload.

The mobile places-import entry point wore an ellipsis, which promises a menu.

The "open in Google Maps" buttons drew the four-segment Google *search* G,
flattened to one colour — a glyph that reads as "run a search". They get a map
pin instead, factored into one component so the desktop and mobile copies stop
drifting apart.
