fix: ensure VT323 font properly applies to FOSSRadar.in logo

Fixed Tailwind CSS 4 font configuration conflicts:
- Removed conflicting @theme font definitions from globals.css
- Tailwind CSS 4 now uses fontFamily config from tailwind.config.ts
- VT323 Google Font properly loaded via Next.js font optimization
- Logo uses font-logo utility class mapped to VT323

Configuration:
- Font import: VT323 weight 400 from Google Fonts
- CSS variable: --font-vt323
- Tailwind class: font-logo
- Applied to all FOSSRadar.in logos across homepage, radar, and project pages
