Add drafts/recent/mine/chapters admin node views

Four NodesController actions -- drafts, recent, mine, chapters --
each building its own base scope, sharing one private method
(index_matching) for search narrowing and pagination. Wizard rewrite
to link into these instead of rendering its own tables is a separate,
later step.

Node.editor_search backs the shared "q" narrowing: an ILIKE substring
match against title/abstract on whichever of head or draft is
present, splitting the term on whitespace and requiring every word to
match somewhere independently, not as one phrase, since real words can
end up separated by markup in the underlying HTML. Deliberately
separate from Node.search, the public content search, which stays
tsvector-based and head-only.

chapters generalizes into /admin/nodes/tags/:tags for an arbitrary
tag list (OR'd, not AND'd), sharing the controller action but
rendering its own template rather than branching inside one view.
