feat(manascore): add live uptime badges from status.mana.how

- generate-status-page.sh now also writes status.json alongside index.html
  Format: { updated, summary: {up, total}, services: { appName: bool } }
- nginx status.mana.how serves status.json with CORS headers (public read)
  and explicit location block to avoid rewrite to index.html
- ManaScore index page fetches status.json client-side on load and
  injects green ● LIVE / red ● DOWN badge next to each app's status chip
