Introduces ISecureCredentialService abstraction and platform-specific implementations for secure credential storage (WebAssembly, MAUI, server). Refactors LoggedInModel to support async auto-login, login, and logout using stored credentials. Updates DI and UI logic to enable seamless auto-login and logout across all platforms. Cleans up redundant navigation checks and improves maintainability.
Introduce IsSyncing and OnSyncingStateChanged to IMgGridBase and MgGridBase for real-time sync state tracking and event notification. Update FruitBankToolbarTemplate to enable/disable the reload button based on grid sync and reload state, subscribing to sync events and cleaning up on disposal. Implement IAsyncDisposable in MgGridBase to prevent memory leaks. Update login navigation to use forceLoad for reliability. These changes improve UI responsiveness and resource management.
