P1 Stream B: port iOS brand assets to Android

- outline, tab_view, app_icon_mark, widget_icon: rasterized from iOS
  PDF/PNG sources at 1024px (gradients/shadows would flatten via SVG trace)
- honeycomb_texture: hand-authored VectorDrawable, seamless hex tiling
  verified at 4x4 render
- widget_icon: adaptive icon (mipmap-anydpi-v26) + density-specific
  mipmap + foreground bitmaps (mdpi..xxxhdpi)
- Source PDFs preserved in docs/ios-parity/source-assets/ for future
  re-rasterization

AssetInventoryTest asserts all 5 Res.drawable entries resolve.
