refactor(big-bang): cards → wordeck im gesamten Code-Layer

Phase 2 des cards→wordeck Big-Bang-Rebrand:

- 4 package.json: @cards/* → @wordeck/*
- packages/cards-domain/ → packages/wordeck-domain/
- 41+12 Files: from '@cards/domain' → '@wordeck/domain'
- pgSchema('cards') → pgSchema('wordeck') (Drizzle-Schema)
- 17 Files: process.env.CARDS_* → process.env.WORDECK_*
- docker-compose Service-Names: cards-* → wordeck-*
- docker-compose Volume: /Volumes/ManaData/cards → wordeck
- env-vars in compose: CARDS_DB_PASSWORD/_API_VERSION/_DSGVO_SERVICE_KEY etc. → WORDECK_*
- Log-Prefixes + Error-Strings + manifest-id 'cards' → 'wordeck'
- CORS-Origin cardecky.mana.how → wordeck.com
- .env.production.example umbenannt + S3-Key entfernt (kein MinIO mehr)

Type-Check 0 Errors in api+domain+web, 51/51 Domain-Tests grün.

DB-Rename + Container/Volume-Rename auf mana-server folgen in nächstem
Commit nach Verzeichnis-Rename.
