This PR modifies both the FE and BE so that we do not fire a single
request for each software policy automation row. Instead, we build the
custom icon url (if any) into the main `policies` endpoint response.
This also prevents 404ing when there's no custom icon uploaded for the
associated software title.
## Testing
- [x] Added/updated automated tests
- [x] QA'd all new/changed functionality manually

For unreleased bug fixes in a release candidate, one of:
- [x] Confirmed that the fix is not expected to adversely impact load
test results
- [ ] Alerted the release DRI if additional load testing is needed
