Video, chosen from the media store

The picker offers it now, and choosing it opens the media picker rather than a dialog. A video is a
PATH, saved as soon as it is chosen: free text needs a draft because writing is something people do
halfway, and picking a file is one act with one outcome.

Edit means whatever editing that KIND means. The canvas draws one button; which door it opens is decided
in the panel, where the kinds are known — so Edit on a video reopens the picker and Edit on text opens
the editor.

Image and Gallery stay named and disabled. Both are things the site already has.
