D0 Part 4: settings visual pass + remaining pages; grep gate zero

- settings.html: Aktív/Inaktív rows -> run-blue check / neutral gray
  (Inaktív no longer red), update states -> run/crit/progress with
  sprite check/x/spinner, pencil + cancel buttons -> icons, storage
  badges -> tags, host-disk bar + JS drive capBar -> meters
  (usageColorClass -> nominal/warn/crit), state-text-* consumers on the
  new suffixes incl. JS-built class names.
- debug.html, app_info.html, storage_init/attach.html, logs.html:
  emoji -> sprite icons or plain text in templates AND JS strings.
- catchall.html (standalone, no sprite): v2 token sweep of its inline
  style, status emoji -> inline SVGs; a stopped app renders neutral,
  not red.
- login.html: two-tone H1 (last word blue-bright).
- setup_hub_versions.html: stale var(--border,#30363d) fallback -> v2.
- Test Group F grep gate: all 34 banned patterns at ZERO across
  internal/web + internal/setup; Scenario E test now asserts the
  '--bg-0: #0A1220' token literal.
