fix(pwa): unregister SW before proxy-reauth reload so Pangolin can challenge

WorkBox's NavigationRoute served the cached SPA shell on window.location.reload(),
meaning Pangolin/CF Access never saw the navigation and the app was left stuck
showing stale offline data. Unregistering the SW first lets the navigation reach
the network so the upstream proxy can run its auth flow.

Also rebuilds server/public with corrected sw.js (health excluded from
NetworkFirst, /oauth/ and /.well-known/ added to NavigationRoute denylist).
