Walkthrough

This change modifies the member email editor component to update CSS utility selectors for typography in Koenig content. Specifically, the font styling for placeholder text and body elements including paragraphs, blockquotes, asides, and list items has been switched from font-inter to font-sans!. The same adjustment applies to nested editor placeholder and content within the .not-kg-prose>div selector. The modification is purely CSS-based with no changes to component logic, props, rendering structure, or event handling.
