feat(amazonq): display transformation history and add ability to resume interrupted jobs (#7781)

## Problem
Users cannot see previous job details (status, project name, job id,
etc) and cannot access the final diff patch. Network issues can cause
jobs to fail on client side while they continue on the backend, and
users have no way to access those artifacts.

## Solution
Repurpose the job status table to show most recent 10 jobs run in the
last 30 days, including links to final diff patch and summary files.
Allow users to retrieve missing artifacts for jobs and to resume
incomplete jobs via refresh button.
