[PP-1] Media library should use styles from Claro

😬 You did not link this from 📌 Media Library integration (includes introducing a new main content renderer/`_wrapper_format`) Fixed , so I did not find this — I created 📌 Media Library dialog styling Active in parallel…

Since 📌 Media Library dialog styling Active contains more detail/nuance, closing this as a duplicate.

That issue is already assigned to you 👍
