Description

Makes use of https://github.com/ibi-group/datatools-server/pull/486. Speeds up the deployment page by not loading in entire deployment object for every entry. Also makes some updates to the mocked server to add a deployment summary endpoint.

Have just run the e2e tests locally and they are failing, suggesting we need to fix the feed source columns

[miles-grant-ibigroup]

Blocked pending feedSource endpoint updates on the backend.

Updated to make use of new fields in https://github.com/ibi-group/datatools-server/pull/491. Will wait for e2e tests to pass and then assign to @binh-dam-ibigroup.

Even though the startDate field is missing, I have defaults set up so it shouldn't impact behavior (aside from the one edge case where the status label will fail to say that a feed which starts in the future starts in the future).
