Fix Android: auto-grant WebView mic permission, match status bar color

- MainActivity: override WebChromeClient to auto-grant WebView
  permission requests (microphone, camera) so the Android runtime
  permission dialog shows instead of WebView silently denying
- Add colors.xml with PedScribe blue (#2563eb / #1d4ed8)
- Update styles.xml: set statusBarColor and navigationBarColor to
  match app theme (fixes brown/mismatched bar at top)
- Change base theme to NoActionBar (removes action bar)
