Add more acceptance test coverage for Submissions/Grants index and detail pages

[jaredgalanis]

What?

Acceptance tests should cover testing the UI elements involved in the submissions and grants index and detail pages.

Why?

When we upgraded Ember most recently to Ember 5 we changed how we fetch data. These changes broke data fetching on data which was fetched implicitly through relationships. This broke the display of data on the aforementioned pages. No Ember or Acceptance tests covered these cases.

How?

Ensure acceptance tests cover all the data we intend to display on these pages.

Acceptance Criteria

Acceptance tests will be added that comprehensively cover the display of data on the submission and grants pages.
