Replace PendingAuth/RSA key passing with tempPassword pattern: - register(): saves keys to disk, stores password temporarily - confirmRegistration(): verifies code, then calls performLogin(email, tempPassword) which re-loads keys from disk - exactly as iOS does - Extract shared performLogin() suspend fn used by both login() and post-confirm flow - Remove PendingAuth data class entirely Simpler, correct, matches reference iOS implementation.
