v0.1.0 — initialer Sprint, vollständige Auth-Reise als SwiftUI

Phase 2 aus dem Native-Auth-Vollausbau-Plan (Option A, siehe
../mana/docs/MANA_SWIFT.md). Entstanden weil drei Apps fast-
byte-identische LoginView.swift hatten und Sign-Up/Forgot-PW
komplett fehlten.

ManaAuthUI-Library mit:
- ManaBrandConfig — App-injizierte Theme-Werte (forest für Cards/
  Manaspur, mana-default für Memoro), Environment-Key, View-Modifier
- Base-Components: ManaAuthScaffold, ManaPrimaryButton, ManaTextField,
  ManaSecureField + .manaEmailField()-Modifier
- ManaLoginView + LoginViewModel — Email/PW-Login, schaltet bei
  AuthError.emailNotVerified automatisch auf ManaEmailVerifyGateView
- ManaSignUpView + SignUpViewModel — Email/Name/PW + awaiting-
  Verification-Hinweis-Screen
- ManaEmailVerifyGateView + ViewModel — Resend-Verification
- ManaForgotPasswordView + ViewModel — Reset-Mail anfordern (immer
  generischer Hinweis, User-Enumeration-Schutz)
- ManaResetPasswordView + ViewModel — neues PW mit Token aus
  Universal-Link
- ManaChangeEmailView, ManaChangePasswordView, ManaDeleteAccountView
  + internal ViewModels — Account-Bausteine
- ManaDeleteAccountView ist zweistufig (Bestätigungs-Wort tippen
  + Passwort) → App-Store-Guideline 5.1.1(v) Pflicht-Surface

26/26 ViewModel-Tests grün via per-test-ID URLProtocol-Routing
(löst Parallel-Pollution zwischen .serialized Suites).
