Usability improvements for the Web Admin Suite

The following usability improvements for the Web Admin Suite have been made.

Label for contact model improved (#669136)

The setting Companies can be the main contact of a case on the Basic tab of the Contact models page has been renamed to Companies can be case contacts. This change clarifies that the option applies to both main and additional contacts associated with a case, rather than exclusively to the main contact.

Template for AI integration scripts updated (#669237)

The template used when creating a new script of the type AI integration on the Scripts page was updated to use current libraries.

Font family and size display improved for rich text templates (#669145)

When editing a rich text template on the Rich text templates page, the font family and font size selectors in the editor toolbar now reflect the formatting applied to the text even if the font family and font size values do not exist as selectable options. This allows the user to identify the text formatting without looking at the source code.
