• I have added documentation for all new/changed functionality (or N/A)

💬 Summary

Resolves theme switching not being uniformly applied across the app. All screens now respond correctly to theme changes at runtime, and the selected theme persists between app launches.

📋 Changes

Theme Infrastructure

• Added radius.large token (20pt) to Auth0RadiusTokens — replaces hardcoded cornerRadius(20) occurrences
• Added themedNavigationTitle(_:theme:) view extension using .principal toolbar slot to colour navigation titles (.navigationTitle() bypasses SwiftUI styling)
• ThemeManager now persists selected theme to UserDefaults

SDK Screens Fixed (Auth0UniversalComponents)

• EmailPhoneEnrollmentView, OTPView, RecoveryCodeEnrollmentView, SavedAuthenticatorsView, TOTPPushQRCodeView — added themed backgrounds,
  toolbarBackground, .tint(), and themed navigation titles
• MyAccountAuthMethodView / MyAccountAuthMethodsView — icon template rendering, themed background and toolbar
• EnrollPasskeyView — replaced hardcoded Color.white and Color("Muted") with theme tokens
• Auth0Loader, ErrorScreen — radius token + safe-area-aware background
• OTPTextField — added cursorTintColor: UIColor parameter, set in both makeUIView and updateUIView
• TOTPPushQRCodeViewModel — moved QR rendering to View; ViewModel now exposes raw URI; View uses CIFalseColor filter to re-colour QR modules with theme colours at render time

Sample App Screens Fixed (AppUIComponents)

• LoginOptionsView — themed background, brand-derived gradient, template icons, themed title
• WelcomeView — template icons, themed logout button, radius token
• SplashView — added theme environment, template Auth0 logo
