fix(codex): reconcile stale Responses WebSocket profiles

[Jonesxq]

What changed

When Responses WebSocket is disabled, reconcile already-managed Codex profiles whose persisted capability metadata is stale. The repair updates both the provider capability in config.toml and every model's prefer_websockets value in the configured model catalog.

Why

Issue #1984 reports that new Codex conversations still retry WebSocket connections five times until the user manually edits config.toml. The routing toggle previously rewrote profiles only when the collection setting changed, so stale profiles survived restarts and repeated saves.
