[Fluent UI] [iOS] Should not zoom when focusing on the send box

[compulim]

Is your feature request related to a problem?

Web Chat is zoomed a bit (like 120%) when the Fluent UI send box is focused.

Will be great if iOS doesn't zoom.

@compulim there are two ways to solve the issue:

• Font size of the textarea should be greater than 16px on mobile Safari
• The maximum-scale=1 added to the meta tag, which will also disable pinch to zoom entirely

I can make a PR adjusting the font-size of input for Safari only
