fix: always-visible export menu + wiki history rev creation

Export menu: dropped the details/summary toggle so format options are
visible at all times; added flex layout with gap for breathing room.

Wiki history: the browser edit form path was calling node.edit() instead
of node.wiki_edit() so revisions were never recorded — /api/v1/nodes/.../revisions
returned empty after every edit. Also tightened the access gate to
can_wiki_edit so non-owner authenticated users can edit wiki-mode root
nodes through the UI (matching the gate already used by the edit-button
macro).
