Update ShellV2 active user icons to use profile pictures

[KCarretto]

This change updates the ShellV2 active user display to show user profile pictures instead of just initials, consistent with the admin page. It updates the GraphQL query to fetch the photoURL and modifies the ShellHeader component to render the image.
