compose: trim themes, attrs and gradle deps for compose-only UI

Drops the legacy AuroraTheme styles, custom attrs and now-unused
styles_widget/styles_text overlays. Updates the dark/light themes,
strings, arrays, dimens and colors to match what the Compose screens
consume. Adds ic_logo_alt and tweaks the launcher/logo drawables.
Trims gradle dependencies tied to the removed Fragment/Epoxy stack.
