Show proper error messages on lifecycle settings page

What does this MR do and why?

Show proper error messages for the following 2 use cases

• When validation fails when attempting to remove a status that is in use, consider providing a link to a filtered work item list with that status

  • UX: Update text to read as below, where link goes to the group level list filtered by status.

    Cannot delete status 'STATUS NAME' because it is in use. View items using status.

• When attempting to apply a status that is deleted, the error is generic. But we already pass a specific error from the backend in the GraphQL response.
