feat(provider,adapter): Codex 默认 body_rules 按 provider_type 维度注册，adapter 全链路传递 provider_type

- 新增 register_provider_default_body_rules 注册机制，将 Codex 特有的
  body_rules 从 EndpointDefinition 全局默认移至 codex plugin 按
  (provider_type, endpoint_sig) 维度注册
- handler adapter 的 build_endpoint_url/build_request_body/get_cli_extra_headers
  增加 provider_type 参数，Codex 判断优先使用 provider_type 而非 URL 匹配
- 前端 getDefaultBodyRules API 支持 provider_type 参数，缓存 key 区分不同
  provider 类型；Codex 路径判断同样优先使用 provider_type
- ProviderDetailDrawer 将 mapping-preview 拆为独立加载，不阻塞首屏渲染
- PoolManagement 补全 KeyFormDialog 缺失的 endpoint/available-api-formats props
- 固定类型 Provider 创建时自动填充 provider-scoped 默认 body_rules
