feat(quinn.www/edge): cache /api/i18n + raise pseo retention to 24h (island mode G5/G6)

Browse source 
- /api/i18n now edge-cached (pseo_cache 6h, serve-stale) so runtime translation
  fetches survive a black/WG outage instead of hard-failing.
- pseo_cache inactive 1h -> 24h so cold /www pages survive a multi-hour outage
  via proxy_cache_use_stale rather than evicting within the hour.
See docs/EDGE_ISLAND_MODE.md.
