-- Bringt die Postgres-Enums `feedback.feedback_category` und
-- `feedback.feedback_status` mit dem `@mana/feedback`-Package in Einklang
-- und legt die `onboarding-wish`-Kategorie für den letzten
-- Onboarding-Schritt an.
--
-- Hand-authored, weil `drizzle-kit push` Enum-Werte nicht zuverlässig
-- umbenennt. Apply manually before next `pnpm db:push`:
--
--   psql "$DATABASE_URL" -f services/mana-analytics/drizzle/0001_align-feedback-enums.sql
--
-- Idempotent: alle Schritte verwenden `IF EXISTS` / `IF NOT EXISTS`-Checks
-- via DO-Blöcke, sodass Re-Runs nicht failen.
