Add Trash affordances: cockpit, listing, dashboard entry

nodes#show gains a Trash section on trashed nodes: provenance from
the trash entry, a restore form whose parent picker pre-fills the
old parent while it still lives, and permanent deletion. A
Move-to-Trash button joins the status actions on living nodes.
nodes#trashed lists trashed subtree roots with weight, provenance,
and deletion; the dashboard housekeeping row links to it, and
trash/destroy redirect there.

Deletion from Trash now removes the whole subtree, deepest first,
each node through a real destroy! so every per-node cascade runs --
amending the never-recursive rule for this one sanctioned path
(both confirms state the count; the root entry carries
destroyed_descendants). Bare Node#destroy still refuses children.
