## 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).

Colors don't work in some cards, menus and the hamburger menu
## Summary
I'm trying to make KDEConnect pull colours from the Material 3.0
wallpaper in Android 12. I've managed to do this to an extent by editing
the xml files in res/values*. There are, however, certain UI elements
that do not respond to the changes I've made, with no obvious files
where their colours may be changed.
## Screenshots
### The devices screen looks great (Except "KDE Connect Devices" in the
App bar isn't themed.)

### The hamburger menu has a white color in light mode. Don't know where
this is set and how to change it

### Three dot menu has a white colour

### Add new devices looks good too

### Not the popup menus though

### Cards in the About section are still white

### Dark mode works fine

### But again, some UI elements like the hamburger menu aren't themed.

I'll keep trying to figure out how to make these elements to their
proper colours, but I've done a lot of searching through the source and
couldn't figure out how. I'm absolutely new to Android development. Help
please.
## Test Plan
For the changes made thus far, none are needed.
