Enable WebAuthn features and improve z-index layering

Adds early enabling of WebAuthn and platform authenticator features in Chromium via command line switches, and injects diagnostics to check availability in the renderer. CSS z-index values are increased for navigation and menu elements to ensure proper layering above <webview> surfaces. Updates Electron to 37.3.1 and expands site-history.json with additional authentication-related URLs.
