Post sits after the tag, not under the ledger

A footer across the panel put Post directly below the ledger in the
bottom dock, since the ledger is the tall column -- so you could read a
figure, hit Post and never pass the tag. An untagged adjustment is
invisible to the bridge and ungrouped in the change log, so the layout
has to route you through that field rather than leave it beside the
work.
