feat(feedback): rename community → feedback (module + routes + domain)

Modul, Routen und Public-Domain heißen jetzt einheitlich "feedback":

- App-Registry: id 'community' → 'feedback', name 'Community' → 'Feedback',
  Icon Megaphone → HeartHalf (passt zum bereits-globalen heart-half-Icon
  am Module-Header und im PillNav-Usermenü)
- Modul-Config: communityModuleConfig → feedbackModuleConfig
- Routen-Refs: alle href/goto-Aufrufe in Modul-Views, MyWishesView,
  Onboarding-Wish, Profile-MyWishes auf /feedback umgestellt
- /feedback/+layout: Brand "Mana Community" → "Mana Feedback", Megaphone
  → HeartHalf, "In Mana öffnen"-CTA zeigt jetzt auf /?app=feedback
- Public-Mirror Domain: community.mana.how → feedback.mana.how
  (cloudflared-config.yml + docker-compose.macmini.yml CORS_ORIGINS +
  PUBLIC_MANA_ANALYTICS_URL_CLIENT). DNS muss separat angelegt werden.
- Settings-Section: Hilfe-Text nennt jetzt feedback.mana.how

Internal: community_show_real_name + community_karma DB-Spalten bleiben
(Migration nicht im Scope dieses Renames). Settings-Search-Index-Kategorie
'community' bleibt ebenfalls — sie spiegelt das DB-Schema, nicht den
User-Begriff.
