feat: Implement local product storage using ObjectBox

Browse Source 
Configures the ObjectBox ProductEntity to allow assigning IDs. Adds a helper to convert ProductStruct to ProductEntity for easier storage.

Saves scanned products directly to the local ObjectBox store.

Updates the ProductListPage to fetch and display locally stored products from ObjectBox upon initialization.

Includes minor UI adjustments in the scanned product component and scanner page, and fixes loading state handling in HomePageModel.
