feat(ansible): schedules read as sentences, each with its own page (#5332)

- The Schedules tab: a verdict line (failing first, paused, next due),
  each schedule as one line (what runs where, how often, when next, how it
  last went); the row opens its page; Run now and Pause stay in the row.
- /ansible/schedules/new and /ansible/schedules/<id>: the form on classes,
  dry run beside the button, the playbook's variables rendered with the
  page; at the foot Delete behind the confirm dialog. ?source=&playbook=
  start a new one on a playbook (Schedule it on the playbook's page).
- A run started by a schedule links to that schedule's page.
- The run page's id guard allows the Run again link's ?from=.
