Disable manual job action button for users without correct permissions

What does this MR do and why?

What: This MR changes the behavior of the manual action trigger button on the pipeline graph - it shows a disabled action button when the user does not have permission to run the manual action, and adds an explanatory hover tooltip.

Why: We don't currently show the action button at all in this case, which leads to confusion about whether the job has a manual action and why a user can or can't run that manual action.

Technically, this MR

• adds the label field to the detailedStatus object that we fetch for a job because this label gets "(not allowed)" appended to it when the user is not allowed to trigger the action
• shows a disabled action button when a manual job doesn't have an authorized action (no job.action is passed in this case) and the label contains "(not allowed)"
• moves the tooltip for the action button to an element that isn't the button itself because disabled buttons can't have tooltips

How to set up and validate locally

1. add a manual action to a public project's .gitlab-ci.yml, here's one I prepared earlier:

stop-staging:
  stage: deploy
  script: echo 'hello'
  when: manual
  environment:
    name: staging
    action: stop

2. run a pipeline for the project
3. navigate to the pipeline page, find the manual action and verify that it is active by hovering over it:
   
4. log out (or open a private browsing window) and navigate to the pipeline page again
5. hover over the manual action and verify that it is disabled and shows the Not authorized to access this job's protected environment tooltip
