We had a mix of specific colors and theme-based Material You colors.
This aims to remove any hardcoded color so the app only uses the colors
from the current theme.
## Summary
Since a lot of devices now have Android 13, some users might want support for the new themed app icons.
This adds support for these, by adding a monochrome drawable (just the default icon with only the phone border and K) in `res/drawable-v24/ic_launcher_monochrome.xml` and then referencing this in `res/minimap-anydpi-v26/ic_laucher(_round).xml`.
## Test Plan
This can be tested by simply compiling and installing the app as usual on any device running Android 13.
After installing the app, the option for an adaptive colour theme will need to be enabled:
- OneUI5: Long-press home screen > Wallpaper and Style > Colour palette > enable colour palette and check "Apply palette to app icons"
- Pixel: Long-press home screen > Wallpaper & style > check "Themed icons"
The app icon should now follow the system theme (on some devices only on home screen, on others both home screen and app drawer).
Adds the Android 8+ style adaptive icons, using the app's highlight color for extra contrast against the current fallback white background behind the white phone border. This new icon follows the size and grid guidelines of material design, and was created as a 108dp@1x svg
