Crash when browsing map due to unhandled exception

I was able to get the mobile app to crash (using desktop build) - loaded a project with a local CRS and then zooming out a lot. This triggered coordinate transform exception: QgsDistanceArea::measureLine() can throw an exception, but InputUtils::screenUnitsToMeters() does not catch it.

(It may be good to do a small audit of the code to see if all QGIS API calls that are marked that thay may throw an exception are handled properly.)

I have a test project I can share (martin/test-cog-webp).

Start at InputUtils::screenUnitsToMeters(), called by ScaleBarKit::updateScaleBar(), and reproduce the crash by opening the project with a local CRS and zooming out. Inspect the coordinate transform path and the listed QGIS API call; done means the map no longer terminates when that transform exception occurs. The issue also suggests auditing other marked-throwing API calls.
