fix(proxy): unify preview/runtime URL rules and proxy checks

- align Codex preview URL building with runtime /v1 normalization

- align Claude full-url detection with runtime adapter patterns

- reflect Claude ?beta=true in proxy preview and avoid query-only mismatch false positives

- enforce openai_chat proxy requirement even when baseUrl is missing

- wire Codex api format selector through ProviderForm and persist meta/config

- fix EndpointField stale async preview race on clear

- add pending feedback for ProxyToggle pre-disable checks

- deduplicate provider baseUrl extraction into a shared util
