Is your feature request related to a problem? Please describe.

In my Wails v2 application, I want to prevent users from zooming in or out using Ctrl + Scroll, Ctrl + +/-, or Cmd + +/-. Currently, the default behavior of the WebView allows zooming, which can break layout, fonts, and UX.

Describe the solution you'd like

It would be great to have a native Wails config option such as:
ZoomEnabled: false
inside the options.App{} struct passed to wails.Run, which disables zooming behavior entirely at the WebView level, ideally in a cross-platform manner (Windows/WebView2, macOS/WebKit, Linux/WebKitGTK).

Describe alternatives you've considered

useEffect(() => {
  const preventZoom = (e: WheelEvent | KeyboardEvent) => {
    if ((e instanceof WheelEvent && e.ctrlKey) ||
        (e instanceof KeyboardEvent && (e.ctrlKey || e.metaKey) &&
        (e.key === '+' || e.key === '-' || e.key === '='))) {
      e.preventDefault();
    }
  };

  window.addEventListener('wheel', preventZoom, { passive: false });
  window.addEventListener('keydown', preventZoom, { passive: false });

  return () => {
    window.removeEventListener('wheel', preventZoom);
    window.removeEventListener('keydown', preventZoom);
  };
}, []);

This works, but a built-in Go-side configuration would be much cleaner and more intuitive.

Additional context

A config option would help keep frontend code simpler and avoid the need to duplicate this workaround in every app. Especially in security-sensitive tools, fixed zoom is crucial for layout control.
