fix(anthropic): let /v1/messages mid-stream failures reach the proxy failure boundary (#44800) 
* fix(anthropic): let /v1/messages mid-stream failures reach the proxy failure boundary

AnthropicStreamWrapper.async_anthropic_sse_wrapper swallowed every upstream
exception and emitted its own Anthropic error frame, so a provider drop on a
streamed /v1/messages call never reached the proxy's streaming boundary — no
failure spend row, no failure callbacks.

Re-raise when the stream is proxy-managed (detached failure hook armed) so
async_streaming_data_generator runs post_call_failure_hook once and serializes
the error frame; when consumed standalone (SDK litellm.messages path), run the
logging object's async failure handler and keep the client-facing error frame.

Fixes #44742

* test(anthropic): satisfy PT012 single-statement rule in mid-stream error test

* fix(anthropic): dispatch both sync and async failure callbacks

* fix(anthropic): dispatch both sync and async failure callbacks

* test(anthropic): move the regression cases into the mapped test file

* refactor(anthropic): read the public detached-failure hook and drop the explanatory comments

* test(anthropic): drive the mid-stream failure tests through a real logging object

* fix(anthropic): re-raise the provider error from the chat wrapper envelope so the router keeps its pre-content retry

* test(integration): cover mid-stream failure bookkeeping of bridged /v1/messages streams

Nine integration cells for the chat bridge: raw httpx and the Anthropic SDK (sync and async) streams that fail after the first content delta now land exactly one failure SpendLogs row carrying the provider's error class, the non-streaming 500, the response-cache twin and a client that leaves mid-stream keep their bookkeeping, a 24-stream burst lands every call id once, and the standalone SDK stream reports the provider error to failure callbacks once.
