feat(cliproxy): pool visibility in quota output and dashboard routing card

- ccs cliproxy quota: per-provider Pool context section with routing
  mode (pool on/off, strategy, affinity, effective retry cap), drain
  order resolved exactly as the selector picks (incl. residual on-disk
  priorities reordering display + drift warning), and per-account state
  named distinctly: available / cooling-until-<time> / paused - these
  produce different client errors so they read differently
- cooling visibility degrades honestly when pool cooling is disabled
  (no cooldown data exists; renderer says so)
- dashboard routing card: pool badge + retry cap + drain-order hint in
  compact and full variants via additive poolRouting state block
- no Bar summary fields, no per-session pin introspection (cut per
  plan); policy_quota_unsupported semantics untouched

Part of #1464 account pools (phase 6).
