Hub redesign, per-language logos, partner carousel, footer + menu fixes

MSOS Hub page:
- "What you can do here": Porsche-style vertical image cards in a
  continuous auto-scrolling marquee with edge fades (real photos placeholders)
- "A glimpse of the space": full-bleed band of 4 connected photos
- "A space we built together": full-bleed image banner with blue gradient overlay
- "Made possible by": partner logo tiles (Cultural Association + Ministry);
  processed Ministry + Cultural Association logos from source art
- Copy/spacing polish; removed em-dashes; larger section spacing; deeper
  final-CTA gradient so it no longer blends into the footer

Branding / partners:
- Per-language MSOS logos (SVG) in header + footer across all pages
- Partner carousel: added Ministry (wide variant), Cultural Association,
  Embassy of North Macedonia, and Spletni Mojster (width-capped); de-duplicated
  logos within each marquee group so new logos appear sooner

Footer:
- Build credit line (Spletni Mojster + Kristijan), clean centered text
- Synced MK/SI footers to EN (added missing About us + Timeline links)

Landing page:
- FAQ short CTA already avatar design (FAQ page kept its Email/Viber block)
- Swapped blurry stock video thumbnail for the real team photo
- Removed the intentional hero-background blur

Navigation:
- Mobile menu: use 100dvh so the language selector is reachable with submenus open
- Desktop: dropdown parents no longer navigate to dead "/#" links

Language suggestion banner:
- Dismissible, browser-language based banner suggesting the matching locale;
  remembers choice in localStorage and waits for the cookie-consent choice
  to avoid overlapping the consent card

Removed stale *.html.bak backup files.
