When user closes app during wallet generation (before backup completion),
app now correctly navigates directly to backup mnemonic page on restart
instead of requiring extra button click on onboarding page.
Changes:
- AuthProvider: Add isAccountCreated, isWalletReady, userSerialNum, referralCode states
- AuthProvider: Enhanced checkAuthStatus() to detect partial account creation
- SplashPage: Add navigation priority for account-created-but-wallet-incomplete state
- SplashPage: Navigate directly to BackupMnemonicPage when account exists but wallet not ready
Navigation priority:
1. Wallet created + backed up → Main page (ranking)
2. Account created but wallet incomplete → Backup mnemonic page
3. First launch or unseen guide → Guide page
4. Otherwise → Onboarding page
