Attach an asset to a page from the asset's own page

The picker moves from assets/edit to assets/show, where the list of attached
pages already is.

A member route, POST assets/:id/attach_to_node, replaces the ride on #update.

Supersedes the picker wiring in the previous commit; what remains of it is
@attach_node in #create, the flash composition and the corrected hint.
