fix: use anchor click to open nostrsigner: URLs in Capacitor WebView

Browse source 
window.location.href causes WebView to try loading nostrsigner: as an
asset URL. window.open(_system) strips query params. The only reliable
method in Capacitor WebView is creating a temporary <a> element and
clicking it — this correctly triggers Android's intent system with the
full URL intact.
