Error handling for network calls

[iLynette]

Story

Add setup for global error management

Acceptance criteria

• When API calls are made, there can be both successful and error response. Manage standard error responses like 401, 403, 404, 500 in a generic way with correct user messaging for different scenarios.
• Any errors that occur during API requests will be caught by the error boundary and passed to the handleApiError function for handling

We will need more info to address this efficiently from the start:

• will we need to make API calls? Will the products page be populated dynamically via NCR/Voyix? Was this part of MVP?
• if so, can we get any relevant info from the client regarding the details of the inventory management system they use?
