fix(ui): launch apps on the page's scheme over HTTPS

New-tab apps and the companion WebView got hardcoded http:// URLs, so a
node reached over HTTPS opened Vaultwarden, BTCPay, Grafana et al in
cleartext. Every app port is gate-owned and serves TLS on the same port
(appgate/tls.rs), so directAppUrl(), the legacy open() path, and
resolveRuntimeLaunchUrl() now follow the page's scheme. HTTP pages (the
kiosk, LAN) are unchanged; netbird keeps its unconditional https.
