Fix light mode favicon to use black Tiles logo

[feynon]

Motivation

• The light theme was showing the white/clear mark instead of the black Tiles logo, so the favicon mapping needs to prefer the black SVG in light mode while preserving the existing dark-mode icon.

Description

• Updated the metadata.icons.icon entry in app/layout.tsx to use /icon.svg with media: "(prefers-color-scheme: light), kept the dark mapping to /icon-dark-32x32.png, and placed the SVG before the .ico fallback so the light-mode vector mark is preferred.

Testing

• Ran npm run lint, which failed in this environment because ESLint v9 expects an eslint.config.* file so lint did not pass; no other automated tests were run.
