-- Admin Moderation Queue — Phase E
-- Erweitert CommunityPost / CommunityReply um Moderation-Felder und legt
-- moderation_actions-Audit-Tabelle an.
--
-- Reported-Marker:
--   isModerated=true  → in /api/admin/moderation/queue gelistet
--   Dismiss           → isModerated=false (Flag clear)
--   Delete            → content="", isDeleted=true, isModerated bleibt true
--                       (für audit / spätere Re-Review)
--
-- Audit-Trail (DSGVO):
--   Jede Aktion (dismiss / delete / ban_user) schreibt einen ModerationAction-
--   Eintrag inkl. content-snapshot. Reporter-Info wird nicht persistiert
--   (anonymous report-flow per Convention).
--
-- Drift-Hinweis: Diese Migration wird via `pnpm prisma migrate deploy` auf
-- staging-/prod-DB gefahren. Lokal NICHT ausführen. Falls Drift erkannt wird:
--   pnpm prisma migrate resolve --applied 20260509_moderation_queue
