CoMaps not listed in microG location apps list (e/OS, Fairphone 5)

Describe the bug:
CoMaps does not appear in microG's location apps list. As a result, the default position is London instead of waiting for a GPS fix.

To Reproduce:
Install CoMaps (v2026.04.07-8) on Fairphone 5 under /e/OS
Open microG settings → Location
CoMaps is not listed among location apps

Expected behavior:
CoMaps should appear in microG's location apps list and use GPS position on startup.

System:
Android Version: 15
Custom ROM: /e/OS 3.7.3-a15-20260506618655-official-FP5

Additional context
OsmAnd works correctly under the same environment without any specific microG integration. CoMaps developers confirmed the issue is not on their side and redirected here (comaps/comaps#4084).

Start by reproducing the issue in microG Settings → Location on Android 15 with CoMaps on the Fairphone 5, then compare the behavior with OsmAnd in the same environment. Trace how installed apps are discovered and listed, and verify that CoMaps appears and waits for a GPS fix instead of using London as its default position.
