feat(ansible): one strip of tabs, a run list that opens on its verdict, a run page in one line (#5328, #5329, #5330)

- section_tabs macro; Runs · Playbooks · Schedules · Inventory on every
  Ansible page, replacing each page's own set of header buttons.
- Runs: a verdict line (last 30 days, failures first with the latest named,
  running now, the schedule due next); under each status what the run did
  across its hosts (ansible/recap.py); a filter bar (playbook, status, who
  started it) that swaps the table and carries into the scroll paging.
- Run page: status, duration, start and who started it in one line; each
  host's result in words, worst first; the playbook it ran links to it;
  the log and failures on classes rather than inline colours.
