UML-2987 Spike PR branch - Not for merge

[MishNajam]

Not for Merge

Purpose

Draft spike branch to still show summary page when image extraction service is down.

Fixes UML-3049

Approach

Recreating the error by mocking with the mock-image-request-handler to return a 500 error with an lpa that already existed. Will need to create a new mock lpa in the mock-data-lpa and mock-image-request-handler side.
