* feat(search): add Microsoft Web IQ provider
* fix(search): require HTTPS for Web IQ credentials
* fix(search): include Web IQ in the packaged endpoint catalog
* fix(search): register Microsoft Web IQ query pricing
* test(search): fix Web IQ exception assertion lint
* fix(search): type Web IQ response passthrough and search error headers
The type-check gate failed on 8 new unknown-type errors in the Web IQ
transformation. Build passthrough fields from a typed helper and validate
the response models directly, and type the base search error headers as
dict[str, str] so subclasses no longer inherit an unknown parameter.
* fix(search): raise Web IQ parse errors without widening the base header type
Typing the base search error headers as dict[str, str] made the shared
HTTP handler report one more argument-type error. Restore the base
signature and raise the same BaseLLMException directly from Web IQ.
