Switch to new Activity.enableEdgeToEdge

[alexvanyo]

This switches over to the new Activity.enableEdgeToEdge call in androidx.compose.

This allows a bit of cleanup:

• We no longer have as much themes.xml logic for the system bar color, as this is done programmatically
• The system bar color is backported even better across API versions
• We can remove accompanist/systemuicontroller as a dependency, since the only usage of it in this project is superceded by Activity.enableEdgeToEdge

There is a small UI change here
Before this change:

After the change:

Previously, the navigation bar was transparent, but after implementing this update, it will overlay a new background. It appears that this layer cannot be removed by setting the navigationBarStyle to SystemBarStyle.auto(android.graphics.Color.TRANSPARENT, android.graphics.Color.TRANSPARENT).

That's what API29+ does by default for 3-button nav. If you want transparent nav bar even for 3-button nav, you can do SystemBarStyle.dark(TRANSPARENT) or SystemBarStyle.light(TRANSPARENT, TRANSPARENT).
