The Rust bridge imported httpx to construct the provider error response, which
fails in the isolated wheel check where httpx is absent. Rust now raises
RustUpstreamError with a headers attribute and the Python lifecycle wraps it in
a typed UpstreamFailure carrying the httpx.Response before legacy mapping.
Test helpers gained call_native so pytest.raises blocks hold a single call

Delete litellm/ocr/input.py and the native _ocr_file_document, _ocr_upload_document
and _ocr_mime_type helpers. File documents now project to a typed OcrDocumentInput
and the core lifecycle reads local paths, encodes bytes and asks the host to read
file-like objects through a ReadDocument operation before the provider request
