Fix iOS input zoom on mobile devices

What does this MR do and why?

Prevents automatic zoom on iOS mobile browsers when focusing on form input fields with font-size less than 16px. iOS Safari and Chrome automatically zoom in when users focus on input fields with font-size < 16px. This is a browser accessibility feature intended to prevent text from being too small, but it disrupts the user experience by unexpectedly zooming the page.
