Steps 4-6: the jobs, the set-up tab with generated scripts, Install the staged folder, site bundles and the campus template

- Overview jobs: Change the playlist, Add or remove a HyperDeck, Add a MIDI link, Add a computer,
  Make a PC program startable; 'Add a key for it' on unwatched Companion connections.
- Computers > Setup: steps with a [how] each and the set-up scripts generated per computer by
  settings/scripts.py from the templates in remote-access/ (no site-shaped value left in them);
  Remove this computer drops the fixes and checks that used it.
- Site setup > Site: the running and staged code, Install the staged folder (a one-shot launchd job
  running install.sh --keep-config, refused while live), Export site bundle (zip), New campus from a
  bundle (this campus's site block stays; every copied computer is flagged until touched).
- sites/: na -> the repo config, _template = the empty campus; install.sh --site <id>.
- Review reads appended checks as 'added'; tests for all of it.
- Deployed page-only to NA Ingest. (config.json, status_panel.py and readiness.py are left to the
  READY-page work in progress in the same tree.)

+# Sites
+
+One folder per campus. `na/config.json` is North Attleboro (a link to the repo's `config.json`, which install.sh
+installs by default). `_template/config.json` is the empty campus: the three fixed keys, this Mac's record and
+nothing else; `install.sh --site <id>` installs `sites/<id>/config.json` when the folder exists, otherwise the
+template. The settings page's **Export site bundle** (Site setup > Site) gives you a zip to drop in as `sites/<id>/`;
+its **New campus from a bundle** starts a campus from another campus's bundle.
