chore(debug): add /debug-realtime page + bare SSE endpoint
Tijdelijke debug-tooling voor M8-acceptance op Vercel preview. - app/api/debug/realtime-stream/route.ts — geen auth, geen filtering; dropt elke pg_notify-event op scrum4me_changes rauw door als SSE - app/debug-realtime/page.tsx — open zonder login op de root, toont binnenkomende events in een simpele <table> Doel: isoleren of de SSE + Postgres LISTEN-pipe op Vercel überhaupt events laat zien, los van iron-session, productfilter of solo-store. Als ook deze niets binnen krijgt: probleem zit in pg connection of Vercel function lifecycle. Als deze wel events toont: probleem zit hoger in de stack (filter, store, hook). VERWIJDEREN voordat de PR uit draft gaat. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
