Wip 0.4.5

Description

Refactor BaseUSPTOClient request methods to eliminate polymorphic return types. The branch splits _make_request (returning dict | T) into three single-return-type methods:

• _stream_request → requests.Response (first commit)
• _get_model → T (second commit)
• _get_json → dict[str, Any] (second commit)

Also adds include_raw_data parameter to DocumentBag.from_dict, StatusCodeSearchResponse.from_dict, and PetitionDecisionDownloadResponse.from_dict for FromDictProtocol conformance, enabling them to use _get_model directly. Fixes PTAB appeals integration test query (Appeal → REGULAR for applicationTypeCategory).

Additional Notes

• 28 call sites migrated across 6 client files: 26 to _get_model, 2 to _get_json (get_search_results POST/GET which do custom list parsing with no top-level model)

• All example scripts pass
• All integration tests pass
• All changes are internal (_ methods), so no public API impact
