New app icon and launch screen from "SyncWave Sv2.png"

- Adaptive icon: the glossy purple S logo, whole image at 94% so the S sits
  inside the 33dp safe zone (it reached 34.6dp untouched), edge blended into
  the new #0E0B14 background that matches the image's border.
- Themed (monochrome) icon: the S as a solid silhouette.
- Launch screen: only the S on #0E0B14, so the round splash crop shows no
  edge of the textured square.
- tools/make_icons.py regenerates all of these from the source PNG.

Verified on the emulator: icon in the app drawer and the launch screen.
