db(cards): baseline migration + drizzle-tracking bootstrap script

Schließt die Ops-Lücke „kein versioniertes Schema-Tracking" aus
FEATURE_IDEAS.md.

* apps/api/src/db/migrations/0000_baseline.sql — Drizzle-generierte
  Baseline-Migration, 355 Zeilen, 25 Tabellen + 5 Enums (cards- und
  marketplace-Schema). Eingefrostet auf den Live-Stand 2026-05-12.
* apps/api/scripts/bootstrap-drizzle-tracking.ts — neues Script,
  markiert die Baseline in einer bestehenden DB als „bereits
  angewandt", ohne SQL erneut auszuführen. Verwendet sha256 wie
  drizzle-orm/migrator (Hash 312d67ba1aeb…), idempotent.
* package.json: drizzle:migrate + drizzle:bootstrap-tracking
  npm-scripts.
* docs/playbooks/DRIZZLE_MIGRATIONS_BOOTSTRAP.md — Hand-Over für
  Prod (Bootstrap einmalig, dann normaler Workflow:
  schema → generate → commit → migrate, kein push --force mehr).

Lokal verifiziert: 17/104 Tests grün, bootstrap idempotent,
drizzle-kit migrate erkennt die Baseline.

+/**
+ * Bootstrap-Script für drizzle.__drizzle_migrations.
+ *
+ * Eine Cards-DB, die bisher über `drizzle-kit push` (Schema-Sync ohne
+ * Migrations-Tracking) gepflegt wurde, hat das Drizzle-Tracking-Schema
+ * nicht. Dieses Script holt das nach:
+ *
+ *  1. Erstellt `drizzle.__drizzle_migrations` (idempotent).
+ *  2. Liest `src/db/migrations/meta/_journal.json`.
+ *  3. Markiert jede dort gelistete Migration als „bereits angewandt",
+ *     mit dem gleichen Hash, den `drizzle-orm/migrator` selbst
+ *     berechnen würde — sha256(file_content) als hex.
+ *
+ * Nutzung:
+ *   DATABASE_URL=postgresql://… pnpm bootstrap:drizzle
+ *
+ * Idempotent: ein zweiter Run macht nichts neu, sondern überspringt
+ * Migrations, deren Hash schon eingetragen ist.
+ *
+ * Nach dem Bootstrap wird `drizzle-kit migrate` jede Migration aus
+ * dem Journal als bekannt erkennen und keine SQL erneut ausführen.
+ * Künftige Schema-Änderungen ⇒ `drizzle-kit generate` ⇒ commit ⇒
+ * `drizzle-kit migrate` führt nur die neuen Migrations aus.

+# Drizzle-Migrationen — Bootstrap und Workflow
+
+Stand: 2026-05-12.
+
+Cards hat bis 2026-05-12 alle Schema-Änderungen über
+`drizzle-kit push --force` gefahren — Schema-Sync ohne versionierte
+Migrationen. Live ist das gefährlich: kein Audit-Trail, keine
+sichere Rollback-Story, schwer reviewable.
+
+Ab Commit `<dieser>` gibt es eine **versionierte Migration-Welt** mit
+einer Baseline (`0000_baseline.sql`), die das bestehende Schema
+festfriert.
+
+---
+
+## Was lokal schon passiert ist
+
+1. `pnpm drizzle:generate` → `apps/api/src/db/migrations/0000_baseline.sql`
+   (25 Tabellen, 5 Enums, alle FKs/Indizes — das gesamte cards- und
+   marketplace-Schema, eingefroren auf den Stand 2026-05-12).
+2. `apps/api/scripts/bootstrap-drizzle-tracking.ts` (neues npm-script
+   `pnpm drizzle:bootstrap-tracking`) — markiert in einer existierenden
+   Live-DB die Baseline als „bereits angewandt", ohne SQL erneut
+   auszuführen.
+3. Lokal verifiziert: Bootstrap ist idempotent, `pnpm drizzle:migrate`
+   erkennt die Migration danach als bekannt.
+
+---
+
+## Was du auf der Prod-Box machen musst (einmalig)
+
+```bash
+ssh mana-server
+cd ~/projects/cards
+git pull --ff-only origin main
+```
+
+### 1. Bootstrap auf der Live-DB ausführen
+
+```bash
+# DATABASE_URL aus der env-Datei lesen, nicht hart codieren.
+DB_PW=$(grep CARDS_DB_PASSWORD infrastructure/.env.production | cut -d= -f2-)
+docker exec -e DATABASE_URL="postgresql://cards:${DB_PW}@cards-postgres:5432/cards" \
+  cards-api node /app/apps/api/scripts/bootstrap-drizzle-tracking.ts
+```
+
+…**oder** wenn das im Container-Image-Setup nicht klappt (Script ist
+TypeScript, der API-Container kommt mit Bun):
+
+```bash
+# Alternative: vom Host aus über Container-Network ausführen.
+# Mac Mini hat Bun installiert.
+cd ~/projects/cards/apps/api
+DATABASE_URL="postgresql://cards:${DB_PW}@127.0.0.1:5436/cards" \
+  bun run scripts/bootstrap-drizzle-tracking.ts
+```
+
+**Erwartete Ausgabe:**
+
+```
+MARKED 0000_baseline (hash 312d67ba1aeb…)
+
+Tracking-Tabelle hat jetzt 1 Eintrag/Einträge.
+```
+
+Wenn statt `MARKED` schon `SKIP` kommt: jemand hat das Script bereits
+gelaufen lassen. Idempotent → kein Problem.
+
+### 2. Verifizieren
+
+```bash
+docker exec cards-postgres psql -U cards -d cards -c \
+  "SELECT * FROM drizzle.__drizzle_migrations;"
+```
+
+Erwartete Antwort: eine Zeile mit Hash `312d67ba1aeb…` und
+`created_at = 1778604624860`.
+
+### 3. Smoke-Test
+
+```bash
+cd ~/projects/cards/apps/api
+DATABASE_URL="postgresql://cards:${DB_PW}@127.0.0.1:5436/cards" \
+  bun x drizzle-kit migrate
+```
+
+Erwartet: `[✓] migrations applied successfully!` ohne dass das
+Schema wirklich angefasst wird (es kommt nur ein NOTICE
+„relation '__drizzle_migrations' already exists, skipping").
+
+---
+
+## Künftiger Workflow
+
+### Neue Schema-Änderung
+
+1. **Editiere das Schema** in `apps/api/src/db/schema/**.ts`.
+2. **Generiere die Migration** lokal:
+   ```bash
+   cd apps/api
+   pnpm drizzle:generate --name <kurz_beschreibend>
+   ```
+3. **Inspiziere** das generierte SQL in `src/db/migrations/0001_<name>.sql`
+   (oder höher) — bei destruktiven Änderungen (DROP COLUMN, ALTER
+   TYPE) ggf. von Hand patchen, damit Daten nicht verloren gehen.
+4. **Commit** Schema-Files + Migration-Files + Journal zusammen:
+   ```bash
+   git add apps/api/src/db/schema apps/api/src/db/migrations
+   git commit -m "db(cards): <was>"
+   ```
+5. **Test lokal**:
+   ```bash
+   DATABASE_URL="postgresql://cards:cards@localhost:5435/cards" \
+     pnpm drizzle:migrate
+   ```
+
+### Deploy
+
+1. `git push` auf Forgejo.
+2. Auf der Box: `git pull --ff-only`.
+3. **Migration anwenden** (kein push --force mehr!):
+   ```bash
+   cd ~/projects/cards/apps/api
+   DATABASE_URL="postgresql://cards:${DB_PW}@127.0.0.1:5436/cards" \
+     bun x drizzle-kit migrate
+   ```
+4. Erst danach Container rebuilden + restarten, wenn der neue Code
+   auf das neue Schema angewiesen ist.
+
+---
+
+## Tabu
+
+- **`drizzle-kit push --force` auf Prod nie wieder.** Das Script
+  bleibt in `package.json` als Dev-Convenience, aber für Prod ist
+  nur `drizzle-kit migrate` der Weg.
+- **Migration-Files nicht nachträglich umschreiben**, sobald sie
+  in einem Prod-Pull-Stand sind — der Hash würde sich ändern und
+  Drizzle würde sie erneut anwenden wollen.
+- **Wenn du das Schema lokal mit `push` schon „weiter" als die
+  Migration hast**, ist das ein Drift-Bug. Lösung: lokal die DB
+  rückbauen (`drop schema cards cascade; drop schema marketplace cascade`),
+  dann Migrationen frisch anwenden. Niemals diesen Drift in einen
+  Commit hineinwachsen lassen.
+
+---
+
+## Bei Problemen
+
+- `pnpm drizzle:migrate` schmeißt „relation already exists" und
+  bricht ab? Bootstrap-Script ist nie gelaufen — Schritt 1 oben.
+- Hash-Mismatch (Migration angeblich „neu" trotz Bootstrap)? Das
+  Migration-File wurde nach dem Bootstrap noch ediert. Entweder
+  Edit rückgängig oder den Tracking-Eintrag von Hand auf den neuen
+  Hash bringen — ausschließlich nach Code-Review.
