chore(brand): rename Cards → Cardecky (display, infra, license-IDs)

- App display name → Cardecky in mana-apps.ts, MODULE_REGISTRY, alle Docs
- Domains: cardecky.mana.how (App), cardecky-api.mana.how (Marketplace
  API), cardecky.com (Marketing-Landing — cloudflared-route + nginx-Block
  vorbereitet, DNS muss noch gesetzt werden)
- 301-Redirect cards.mana.how → cardecky.mana.how (nginx + cloudflared)
  für alte Bookmarks; kann nach 6–12 Monaten wieder raus
- SPDX license IDs Cards-Personal-Use/Pro-Only-1.0 → Cardecky-* via
  Drizzle 0001-Migration (DROP CHECK → UPDATE rows → SET DEFAULT → ADD
  CHECK), inkl. _journal- und 0001_snapshot-Update
- In-mana cards-Modul: dezenter Banner zur Standalone-App (GUIDELINES
  §12), einmal schließbar via localStorage
- Docker-CORS-Listen, sso-origins.ts, Prometheus-Target aktualisiert

Technische IDs bleiben bewusst: appId 'cards', schema
mana_platform.cards.*, Verzeichnis apps/cards/, Package @cards/web,
services/cards-server, Env-Vars CARDS_*, UMAMI_WEBSITE_ID_CARDS*, Class
CardsEvents — Mana-Konvention (Brand ≠ technischer Identifier).
