Phone app: Google map tiles when a key is available - #13
Merged

Conversation
The phone map now draws Google's tiles (Map Tiles API) when the APK is built with NEXT_PUBLIC_GOOGLE_MAPS_API_KEY in .env.local, the desktop app's browser key. Without it, or when Google can't be reached, it falls back to OpenFreeMap, and offline to the plain background with pins and routes. The Map Tiles session is reused for its lifetime, dark mode gets a dark Google look, and the map shows Google's logo with the copyright for the area in view. Only that one variable is exposed to the build; the source never contains a key. README and .env.example say the key ends up inside such an APK, so it should not be shared.

* Show the day's map and route in the phone app A map band sits above the day's plan and stays put while the list scrolls, so dragging the map never fights the page. It can be hidden (remembered) or opened full screen; Android back closes full screen first. Tapping a pin scrolls to its card; tapping a card brings its pin into view. In full screen a tapped pin shows what it is (a tour stop names itself and its tour) with a way back to the plan. Pins, route lines and tour stops come from lib/mapLayers.ts, now shared with the desktop map, so both draw the same thing. Route shapes are read from the trip file; without network the map falls back to a plain background, keeping pins and routes readable offline. MapLibre loads only once a trip is opened. The morning's hotel pin is left out when a card sits at the same spot (a tour picking you up at the hotel), where it hid that card's numbered pin.

Summary
Builds on #12 (the phone app's day map); merge that first. This PR only changes the map underneath the pins.
NEXT_PUBLIC_GOOGLE_MAPS_API_KEYin.env.local(the desktop app's browser key, with the Map Tiles API enabled), the phone map draws Google's tiles through the official Map Tiles API. MapLibre stays, so pins, routes, tour stops, full screen and the pin ↔ card link are unchanged.Keeping the key out of the repo
mobile/vite.config.mtsexposes only that one variable from.env.local(gitignored) to the build..env.examplewarn that the key ends up inside such an APK, so it shouldn't be shared or published.Note for offline maps (next step)
Google's terms don't allow storing tiles for later, so downloading maps for offline use will keep using OpenFreeMap.
