Step 0 of the settings page: registry, safe restart, remembered state, test verb, page markers

- schema.py: every setting with type, default, help, owner screen and the rules a config must
  pass; tests/test_schema.py keeps it in step with the code (every key the code reads is declared,
  every default matches, check types and fix kinds agree, the glossary covers every word a key can
  show, today's config still builds today's pages apart from the key notes)
- status_panel.py: VERSION + started.json; SIGTERM lets a running fix finish and starts nothing new
  (RESTARTING SOON); fixes-running.json and live-now.json for the settings page; state.json keeps
  the ALARMS override, acknowledgements, auto-fix tries and fix times across restarts, keyed by
  what a check is about rather than its position; 'test' and 'resurvey' commands; queued commands
  dropped at start; overnight windows; a HyperDeck switched off is always switched back on;
  the spotify fix kind (playlist set once, in config 'spotify'); Windows remote checks batched for
  cmd.exe with conditional echoes; every fix's kind and host validated; never_auto; wording and
  numbers from config (site block, timing, page_hold_ms, auto-fix keep_months); hyperdeck_probe
  removed; --check and --exit-timeout
- make_page.py: numbers from config, markers on every key, nav templates per Companion version,
  --out; push_page.py: a page is overwritten only when every key carries a marker (foreign keys
  named by position), secret-free fetch, host from the site; nav_keys.py: host from the site;
  netgear.py: switches and the shared-port limit from config
- install.sh: validates with the new code first, keeps prev/ for --rollback, --keep-config,
  derived ExitTimeOut, wider deploy list, waits for the start stamp
- config.json: site, timing, spotify sections; Windows hosts marked; deployed to NA Ingest and
  both pages re-imported once (--force) so every key carries its marker
