Generated portal pages get per-section headers; module list scrolls

Each generated section (Draw a map / Make a submission / Map gallery
or Submissions) now opens with its own section_header block so the
default page reads as distinct sections — editors rename or delete
them like any other block. The wizard's module checkbox list is capped
at 50vh with scroll overflow so long module catalogs stay navigable
alongside the type-to-filter box.
