Merge origin/main: reconcile briefing checklist and brief visuals

Both branches added a case-briefing checklist independently. Reconcile onto
the upstream {id,text} BriefChecklistItem model and keep the upstream brief /
luggage-tag visual refinements (boxed CHECKLIST section, assignment/heading
split), while retaining this branch's full-stack backing (checklist table,
board read/write/clone, importer/exporter) and the player-tickable interaction
(persisted locally per level). Keep the brief-goals list alongside the new
checklist. Align the server wire shape, importer, and exporter to {id,text}.
