Press: add /press/ page (EN/MK/SI) + footer link + coverage list

- New Press & media page in all three languages: press-enquiries contact,
  a 6-way logo download grid (EN/SI/MK x colour/white), an "MSOS at a glance"
  fact sheet (full legal name + preferred name), and a grouped coverage list
  (media, universities & institutions, official records, reference, government)
  with 29 verified third-party links, each described in EN/MK/SL.
- Styling in css/pages/_press.css (imported by main.css), on the site's tokens.
- Footer: added a "Press & media" link to the Organisation column on every page
  (all languages, relative paths correct for each page depth).
- SEO/sitemap refreshed so the new pages carry NGO schema + hreflang.

MK/SI copy is AI-drafted and pending a native proofread.
