Vendor language flags locally and add scrolling partners marquee

Flags: replace flag-icons CDN with local SVGs (images/flags/{gb,si,mk}.svg) referenced as CSS backgrounds, so no external dependency and no per-page path issues. Partners: replace the static home-page logo row with a seamless auto-scrolling, hover-pausing marquee (CSS-only, reduced-motion aware, edge fade).
