BCDA-7786: Create Job Keys for ndjson files

[laurenkrugen-navapbc]

🎫 Ticket

https://jira.cms.gov/browse/BCDA-7786

🛠 Changes

• processJob: moved code to create job keys and update job status into its own function for testing
• processJob: moved file size check into writeBBDataToFile
• processJob: creating keys for each Job Key that is returned
• writeBBDataToFile: changed return values to be a list of JobKeys and an error
• writeBBDataToFile: returning "*-error.ndjson" job key if it is created (was not being returned and did not have job keys previously)
• update to pre-commit / golangci-lint to check the pkg, as linting was failing on single files.

ℹ️ Context for reviewers

error.ndjson files not having job keys written to the database and middleware checks for job keys failing to serve HTTP. These changes will return the ndjson file and pass the middleware check, if the file exists.

✅ Acceptance Validation

Current tests pass, some tests modified, new test added. Lots of intertwined dependencies with this one; was difficult to test.
