Begin style migration to Material3

Use large card view rounded corner guidelines

Fix action bar theming

Needed to import android back button clip art to fix material 3 theming issue. The DolphinSettingsBase style used to inherit from the Theme.MaterialComponents.DayNight.DarkActionBar theme which would provide the light text and icons but this is no longer available with Material 3.

Fit box art more snugly in CardView

Change card height to match cover art

Add padding to top of games list recyclerview
