fix: ITMS-90129 — DisplayName Cards → Cardecky + Build 2

Apple lehnte Build 0.1.0(1) ab mit ITMS-90129: "The bundle uses a
bundle name or display name that is already taken." Im App-Store
gibt es schon Apps mit dem DisplayName "Cards" (u.a. Apples eigene
Grußkarten-App war so benannt). App-Store-Connect-App heißt sowieso
"Cardecky" — Brand-Konsistenz: DisplayName durchgehend "Cardecky".

Geändert:
- project.yml Main-App: CFBundleDisplayName Cards → Cardecky,
  CFBundleVersion 1 → 2 (Apple lehnt doppelte Build-Nummern ab)
- project.yml Widget: CFBundleDisplayName Cards Widget → Cardecky Widget,
  INFOPLIST_KEY_CFBundleDisplayName analog
- project.yml Share-Extension: CFBundleVersion 1 → 2
- LoginView Heading: "Cards" → "Cardecky"
- NotificationManager.content.title: "Cards" → "Cardecky"
- UITest: erwartet "Cardecky" statt "Cards"

Archive verifiziert: CFBundleDisplayName=Cardecky, CFBundleVersion=2,
ARCHIVE SUCCEEDED. Nach erneutem Upload via Xcode Organizer sollte
TestFlight den Build akzeptieren.
