I've added a three-dot options menu next to each user's name in the Linked Users table. The menu includes a "Remove role" option that allows you to remove the role from individual users. This provides a more granular way to manage role assignments alongside the existing bulk remove action available when selecting multiple users via checkboxes.

I've updated the header buttons as requested: removed the "Share form" button, changed "Test form" to "Test mail", and replaced "Publish changes" with "Edit" that includes a pencil icon for a cleaner, more focused action toolbar.
