Feat/amui/1101 unhappy flow ikke alle rettigheter delegert

[sonwit]

Description

• Handle errors and partially failed delegations.
• Fix snackbar
• Add alert for screen-readers
• Adding some storybook test-data
• Refactor MSW handlers

note:

It's difficult to test the functionality of a partially failing delegation without real-world data. My hypothesis is that it will look more accurate once we have access to actual data. Invalid data will then be refreshed, and the modal will display the current state. Currently, these changes are not displayed, which might lead to an unexpected user experience.

Great work! 😄

I agree that the intended user experience is hard to display with only static test data. It will likely be a lot better once invalidating cache gives us an actually updated state based on the action the user just performed. But this is the best we can do for now, I think. We'll just have to make sure it all works as intended once we get the backend online as well.
