fix(web): use marketing Antigravity icon in settings

[voltcrash]

Depends on #13231. This branch starts at the marketing icon fix. GitHub's upstream diff includes that parent change until it merges; review the Settings-only diff for this PR's change.

The web provider icon still showed the older PNG with its built-in dark tile. Downscale the transparent Antigravity artwork from the marketing site to 128 × 128 and embed the resulting PNG as base64 in AntigravityIcon. The marketing image stays unchanged. This updates Settings → Providers and other web views that use the icon.

Summary by CodeRabbit

• Style
  • Updated the Antigravity icon’s size and presentation across the marketing page and app. The icon appears larger in harness displays, while the floating hero card uses a simpler card appearance with a smaller image. These adjustments provide a more consistent visual treatment of the Antigravity icon across the affected screens.

Approvability

Verdict: Approved at 3bb2332

Macroscope's review found this PR approvable — This is a narrowly scoped Antigravity icon replacement affecting only marketing presentation and web UI rendering. The web build continues to use established bundled-asset imports, with no changes to provider behavior or product defaults.

The marketing hero displays a smaller Antigravity mark, but this is a localized presentation change; the web icon retains effectively the same artwork. No material merge-blocking behavior is evident.

Superseded by #13373, which already landed the transparent Antigravity mark in apps/web/src/components/Icons.tsx (and mobile). Closing this as leftover hygiene — the marketing half stays on #13231 / #13365.
