RFE: Build-time configured distro logo in the greeter and lockscreen

[Conan-Kudo]

I would like to have the Fedora logo prominently shown in the COSMIC Greeter and lockscreen. Currently, no such logo is present:

Compared to SDDM:

And GDM:

Could we get some kind of similar build-time configuration knob to show the correct logo based on light/dark setups?

Just as a little thought experiment. This is could easily be a simple layer-shell client, started by the greeter script or through a user-service for the cosmic-greeter users session without any modification to our code.

(Though that wouldn't work for the lock screen, just the login screen.)
