feat: new "card fan" app icon — web favicon/PWA + Android adaptive

- Master SVGs + generator in scripts/icon/ (icon.svg full design, icon-foreground.svg
  cards-only for the Android adaptive layer, gen-icons.mjs via sharp).
- Web/PWA: regenerated favicon.ico (16/32/48), src/app/apple-icon.png, public/icon.svg,
  icon-192/512, icon-maskable-512; manifest now lists png + maskable icons.
- Android (Capacitor): ic_launcher / ic_launcher_round / ic_launcher_foreground for all
  densities + ic_launcher-playstore 512; adaptive background switched from flat white
  to a navy radial-gradient drawable (matches the icon), foreground = the gold card fan.

Design: navy field, gold rounded frame, three fanned cards with a gold spade —
on-brand with the in-app "Persian luxury" look.
