Refactor SignalR, pallet editing, and error handling

- Refactored SignalRMessageToClientWithText<T> to use explicit constructors and properties.
- Added Shipping.Comment column to GridShippingDocument.razor.
- Updated PalletItemComponent: renamed audit callback, added pre-save/audit callback, improved UI refresh logic.
- MeasuringOut now uses new callbacks and _enablePalletItems flag to control editability during save/audit.
- Wrapped SignalR message handling and logout logic in try/catch for better error logging.
- MainLayout and MeasuringOut now implement IDisposable to unsubscribe SignalR events.
- UI editability and state updates improved for thread safety and responsiveness.
