#5093 "Shared format filters and status_class driven by Settings → Thresholds".

- steward/core/formatting.py: human_bytes (binary units), human_rate,
  human_duration (two largest units), ago (a <time> titled with the absolute
  UTC time) and status_class(value, kind, thresholds) -> ok/warn/crit/unknown,
  which raises on a kind the thresholds don't name.
- app.py registers them as the bytes, rate, duration and ago filters and the
  status_class global; threshold_style is now graded by status_class (and caps
  its weight at 500).
- Replaces the copies: docker's _human_bytes/_human_uptime, core alerts'
  _duration, the host-agent fmt_bps/fmt_bytes macros, the Traefik and UniFi
  byte-rate arithmetic, the swarm-failures ago macro and two uptime spans.
- Tests: a table per helper, and every template compiled against the app's
  filters, so an unknown filter fails CI rather than a page.

bvandeusenandClaude Opus 4.8 9e4f1983f8 feat(host_agent): lazy-load full-metrics charts + live-poll current state
CI / lint (push) Successful in 2s

CI / unit (push) Successful in 51s
CI / publish (push) Successful in 1m10s
The full-metrics page rendered once server-side with the history query inline,
so the charts blocked first paint and nothing refreshed without a reload (it
reads the latest snapshot the server holds — the agent pushes ~every 30s).

Split it into a shell + two HTMX fragments:
- Shell (host_detail.html): header + shared time-range toggle + two containers;
  paints instantly.
- Current state (/<id>/metrics → _host_metrics.html): identity + gauges +
  per-core + filesystems + interfaces/disks + temps, from the DISTINCT ON latest
  query. hx-trigger "load, every 15s" → live numbers at ~the agent cadence.
- History charts (/<id>/charts → _host_charts.html): the 3 charts + Chart.js,
  from the date_bin history query. hx-trigger "load, every 60s, rangeChange" so
  they lazy-load (never block paint), refresh slowly, and follow the range
  selector. Leak-safe: previous Chart instances are destroyed before re-render.
- Range toggle switched from full-reload links to the shared _time_range.html
  (setTimeRange + rangeChange), so only the fragments refetch.
- routes: host_detail (shell) + host_detail_metrics + host_detail_charts, with a
  _split_host_metrics helper.
- tests/test_templates_parse.py now also parses plugin templates (these
  fragments aren't rendered in the unit lane).
