// Ditampilkan sesaat setelah user berhasil connect ke server (dari
// ServerConnectScreen) atau saat app dibuka dan serverUrl sudah tersimpan.
//
// Logic:
// 1. Delay singkat 500ms untuk animasi logo.
// 2. Baca accessToken dari SecureStorage.
// 3. Jika tidak ada → redirect /login.
// 4. Jika ada → baca role → redirect /user/walkguide atau /guardian/dashboard.
//
// TTS "Welcome back, {displayName}" jika auto-login (token sudah ada).
