redesign screen-1 and screen-2, add pub status API and FAQ

- add hero video to screen-1 with local Dune Rise font replacing Google Fonts
- screen-2: replace cards with interactive FAQ accordion (6 questions + 5 nested)
- add SSB pub node status monitor with live API polling
- add Flask API (/api/status/ssb, /api/status/ecoind) proxied via nginx
- full responsive CSS rewrite (1024px, 768px, 480px breakpoints)
- strip all accent marks for Dune Rise font compatibility
