feat(ansible): Playbooks as one list, and a page per playbook that runs it (#5331, #5330)

- /ansible/playbooks lists every playbook across sources: what it says it
  does, its category and destructive flag, how it last ran; the whole row
  opens the playbook. A source with none is one quiet line.
- /ansible/playbooks/<source>/<path>: the verdict (what it does, flagged
  destructive, last ran), the run form in place (dry run beside the button,
  options folded), the schedules that use it, its recent runs, the playbook
  itself folded. ?from=<run> fills the form from that run: Run again on a
  run's page.
- /ansible/browse, its view page and the /run-form fragment are gone, not
  redirected (rule 122); every link points at the new pages.
