We have discussed the possibility of using HAL links in the JSON to avoid encoding issues and other logic bugs in the application. This ticket has a small surface area where we can test some of the integration.

1. Update the BlueMessageEnricher to return a HAL-compliant URL for the blueocean_rest_job_url
2. Update identity logic in RunPipeline, api/Pipeline, api/Branch, OrganizationPipelines and actions to check for identity based on the URL.
3. Update REST fetching logic to use the appropriate "runs" link (ideally) or by appending "/runs/" to the self URL.
