There is no more `video-playlist` shortcode. To use video, it is now `[playlist type="video" ....]`. Also deleting core playlist styles. The `style` attribute is still supported, defaulting to `light`. Our core style support was 4-5 CSS rules. 

See #27552. Leaving open for comments and potential bugs.

Affix the audio view toolbar to the bottom as opposed to the top of the view. Otherwise it's not accessible when the view is the first item in the content. Said views keep a newline underneath, so there's space for it to appear there instead. fixes #27548, see #27320.

In `multi_resize()` image editor methods, assert that `null` can only be passed for one of the arguments, not both. Add a lot more unit test assertions to ensure this.

Edit Image modal:
- Bring back some of the advanced settings.
- Make the layout two-column for wider screens, remove the sidebar, and shrink the modal a bit.
- The image reflects the size as inserted in the post as long as it doesn't overflow the column and is not too tall. Changing the size to another intermediate will also update the image "preview."
- Rename "Edit Image" to "Edit Original" to try and better communicate that editing the image will modify the media library item not just the image inserted into the post that is being edited.
(updates two PNGs from precommit)
