Incorrect error handling reported in Play Console

EdgeToEdge is implemented previously, this enables a Play Console
suggestion.

Mostly using Gemini, some manual fixes and updates to comments etc.

For markers, use popup instead of displaying on map.
In addition to time/instace, include current pace/elevation/hr.

Followup to previous AsyncTask migration.
Partly using Gemini, but manual fixes required.

Many no longer needed with minsdk >= 21

no longer needed since sdk 21 > 17
right/left attributes can be removed

All automated changes.
Primarily use of Java records.

Cherry picked warnings that seem relevant

to avoid deprecated Gradle usage
remove the variants for specific hardware.
This was not used by Play or F-droid, only private builds.

Especially for extensions

Use the (beta) androidx libraries to adjust the WGS84 elipsoid
to EGM2008 se level elevation.
The functionality is built in to Android 14 and later and available in
androidx libraries (that may require that the libs are downloaded).
The previous implementation used a custom EGM96 model bundled with the app.
