[codex] feat(tui): show provider reasoning readiness

[Hmbown]

Summary

• Adds ProviderReasoningSummary to /provider dashboard rows so the projection can expose reasoning support, accepted controls, stream visibility, and the currently configured control.
• Renders the reasoning badge in the compact provider row hint while preserving the existing route/base/catalog facts.
• Seeds GLM reasoning controls as catalog-shaped provider+wire data and reuses Codex effort labels so Codex displays xhigh without model substring inference.

Refs #3083

Closing this older dirty draft as superseded. The provider reasoning/readiness slice landed through #3555 on current main with the catalog-backed projection, provider dashboard tests, and green CI, and #3083 is now closed by that merge.

Thanks to the earlier draft for shaping the path; the shippable version is #3555.
