Add CoMaps, the offline OpenStreetMap navigator, alongside the existing map integrations. A geolocated place gains a CoMaps entry in its navigation menu, and a day's route toolbar gains a button that hands the day's bookended stops to CoMaps in that day's travel mode. CoMaps' route link carries only a start and a destination, so a two-stop day goes as a route and a longer one as named pins rather than silently losing the stops in between. Links use the https form so a device without CoMaps installed lands on comaps.at instead of a dead scheme. The hotel-bookend logic behind the Google Maps export was duplicated between desktop and mobile; both now share dayExportStops so the two links cannot disagree about which hotel legs are real.

* Open a place in CoMaps, the privacy-focused offline OpenStreetMap navigator.

|
|
* The https form rather than the `cm://` scheme CoMaps also answers to: both open
|
|
* the app when it is installed, but only this one has somewhere to land when it is
|
|
* not — comaps.at, which is the install page. A PWA cannot ask whether an Android
|
|
* app exists, so the fallback has to be the link itself.
|
|
*
|
|
* Coordinates are required: CoMaps places the pin from `ll` and uses `n` only to
|
|
* label it, so a name on its own has nothing to attach to.
