feat(nginx): cards.* + cardecky.* → wordeck.com 301-Redirect

Cards-zu-Wordeck-Cutover-Phase Ω-6: alte Legacy-Hostnames werden auf
die neue Domain umgeleitet.

- cards.mana.how + cardecky.mana.how → 301 → wordeck.com
- cards-api.mana.how + cardecky-api.mana.how → 301 → api.wordeck.com
- Tote cardecky.com Marketing-Landing entfernt (war nie deployed)

Hinweis: cloudflared routet cardecky.mana.how weiterhin direkt zur
cards-web — alte Native-App (Bundle ev.mana.cardecky) braucht das.
Der 301 hier greift erst, wenn cloudflared umgestellt wird.
