feat: daemon health panel, brand-rail status chips, user timezone selector

- Health API now surfaces Docker /info + /version (version, platform,
  kernel, container/image counts, storage driver, memory, latency) and
  NPM aggregates (proxy host total, managed-by-Tinyforge count, access
  lists, certificates, endpoint URL).
- Docker/NPM indicators moved out of the sidebar footer and into a
  compact mono-styled rail directly under the Tinyforge brand title,
  with pulse/fault animations and click-to-expand error hints.
- New SystemDaemonsCard on the dashboard: two terminal-styled panels
  (Docker Engine + Proxy) with a running/paused/stopped stacked bar,
  key-value diagnostics, and a total-vs-managed proportion meter on
  the proxy-hosts tile.
- Shared health store so the sidebar and dashboard share a single
  30 s poll instead of duplicating traffic.
- User-facing timezone preference with auto-detect fallback; all
  dates across projects, sites, stacks, settings, backup, event log
  and stale containers now render through \$fmt.date / \$fmt.datetime.
- en/ru translations for both features.
