Make the exceedence comment box resize

6.1.26 - signed off on staging and ready to upload to live system

11/12/25 Updated: Ellipsis now working for content extending byond the limit of the text box and content spread over multiple lines.

Applies to comments and measures taken.

I think we should pause the page refresh when this Alerts section is active. It's a bit annoying having it refresh when one is in the middle of typing.

Update the exceedences comment box so that users can input muliline comments with box resizing to display all text when active.

When the box is not active display as a standard input with ellipsis to indicate overflow.

Put on staging first.
