iOS: load inline spinner HTML (centered spinning ring on dark background)
before navigating to the real content URL. Supports light/dark mode via
prefers-color-scheme. The spinner is replaced when the real page loads.
Android: use a native ProgressBar overlay instead of HTML — the HTML
spinner froze because constant Capacitor bridge calls saturated the
main thread, starving the WebView compositor. The native ProgressBar
animates on the render thread independently. Wrapped in a FrameLayout
with a dark overlay behind the spinner.
Both platforms: set WebView background to #14161f (app dark theme)
instead of white. Increased Android shouldInterceptRequest timeout
from 10s to 60s to prevent premature timeouts on large nsites.
