- App display name: 'TipToi Sync' -> 'tiptoi Sync' (strings.xml,
capacitor.config.ts).
- New app icon: stylized tiptoi pen (orange body, grip band, sensor
tip) on dark background, regenerated for all mipmap densities plus
the adaptive icon foreground and round variant.
- Matching splash screens (portrait + landscape, all densities) with
the same pen motif centered on the dark background.
- Web favicon updated to match.
- Removed unused legacy vector icon assets
(drawable/ic_launcher_background.xml,
drawable-v24/ic_launcher_foreground.xml) that were superseded by the
raster icons.
