feat: Unraid deploy, dealer-flow heatmap, confluence zones, 13F capture

Ship Node production images, Unraid compose, and Gitea CI/CD (test then
push registry images; cron script if no runner). Rebuild dealer flow as a
heatmap-first map with integrity gates and chart helpers. Add confluence
zone rules, session clock, capture evidence, and tighter 13F/queue/options
paths, plus the matching UI and tests.
