Poster Sections becomes a parameterized profile like doxa-simple-map: its
props (type, scope with 'all' = every region, locale, columns, collapsed)
choose the <dxm-poster-section> sections it renders, and
poster-sections.instances.json lists 20 presets, each built into its own page
and embed snippet in manifest.json:
- country posters: all regions + each of DX Life's /regions regions (8);
- UPG 100 posters: all regions + each of its 9 regions (they show once the
upg100-list type is registered on the page);
- configure: the panel of choices and Copy embed, for making new presets.
The element's columns attribute now comes from the library (landing
separately), so this commit drops its library edits; check:poster-sections
reads columns back through that attribute and passes once it is on the pilot.
