Restructure nodes#show and nodes#new around node_description/node_content

nodes#show's flat <table> of label/value pairs grew unreadable once
Admin Preview and Public Preview were added alongside Public Link -
switched to the div.node_description/div.node_content pattern already
used by nodes#edit, grouped into People/Dates/Links/Revisions/Tags/
Events/Children sections rather than one undifferentiated list.

People/Dates/Links use a flex-based item layout, not a second <table> -
multiple independent tables sharing one outer width but different
column counts produced misaligned columns with no shared grid. Flex
items size to their own content with a shared minimum instead.

Revisions and Children are both collapsed via <details>, no JS needed -
previously nodes#show didn't list a node's children at all, blocking
the ability to find/navigate erfa and chaostreff pages without already
knowing they're now standalone nodes. Revision list items link to
node_revision_path(@node, page) - the actual per-revision diff/restore
view, not the plain index.

nodes#new converted to the same pattern for visual consistency, plus a
few things surfaced along the way: submit buttons were unstyled
site-wide (a bare input[type=submit] with no border, fill, or hover
state - Create on this exact page was easy to miss entirely), fixed
with a bordered/bold treatment reusing the existing form.button_to
visual language rather than introducing a fourth button style. Title
regained the bold weight it had before the table rewrite dropped it
silently. Tag list grouping and full link/button semantic taxonomy
(show vs edit/add vs publish/revoke vs destroy, applied consistently
across every link on the page, not just buttons) are known follow-ups,
not attempted here.
