* Add embedded market grids
* Hacky way to set height
I haven't figured out a way yet to get the height of the actual iframe's content, so I did some bad estimate for now to unblock shipping the feature, while I continue investigating.
* Try embedding iframes in tiptap
* When iframe code is pasted, inject it into the editor
* Code cleanups and comments
* Remove clsx dependency
Cuz it doesn't exist in `common` anyways
* Rename to tiptap-iframe
