Fix Official information page: hero layout, short name, SKD activity

- Fix the hero: override the global flex-row .container so the eyebrow,
  title and lead stack and centre (they were laid out in a row)
- Short name -> "Društvo MŠOS za študentsko podporo in kulturno sodelovanje"
  (official kratki naziv, normal case) instead of "MSOS"
- Add the main activity row: SKD 94.999 (activities of other membership
  organisations n.e.c.), and relabel S.15000 as the institutional sector
  (SKIS). All three languages.
