* fix: Answer Anthropic envelopes on Messages auth failures without relabelling unmapped statuses

* fix(proxy): answer the Anthropic error envelope on the /anthropic pass-through
The pass-through relays upstream errors in Anthropic's shape, but the proxy's
own refusals there (bad key, model access, budget) still answered the OpenAI
body, so an Anthropic SDK pointed at /anthropic could not read them
* fix(proxy): answer the Anthropic envelope for 404, 405 and unhandled 500 errors on Messages routes
A disabled Claude Code gateway 404, a wrong-method 405 and an unhandled 500 on the
Messages and /anthropic/ routes kept FastAPI's detail body or the OpenAI shape. The
central HTTP and unhandled-exception handlers now pick the Anthropic envelope by route.
The dashboard playground toast titles Anthropic error types when the body has no code.
* fix(proxy): keep LiteLLM error types and Anthropic envelopes on Messages routes
Error bodies on the Messages routes now carry error.litellm_error_type when the
LiteLLM type differs from the Anthropic type, so clients and the Admin UI keep
causes like budget_exceeded. Unlisted 4xx statuses map to invalid_request_error
per Anthropic's errors page, model-list requests that send anthropic-version get
the Anthropic envelope, and the admission, decompression and request-size
middleware errors use it on these routes too.
* test(proxy): expect litellm_error_type in Messages integration tests and type middleware tests
* fix(proxy): keep handler error bodies unchanged and timeouts as api_error
Errors the Messages and count_tokens handlers already returned in the Anthropic
shape keep their original bodies, so litellm_error_type now appears only on
errors the proxy raises before the handler. A 408 stays api_error as before,
and the playground toast titles the new Anthropic types and ignores long
numbers in front of an embedded error
* fix(proxy): keep the base error types inside the Messages handler and scope toast titles to Anthropic bodies
The wider status table (402 billing_error, 409 conflict_error, 504 timeout_error,
other unlisted 4xx invalid_request_error) now applies only to errors the proxy
raises before the handler. Errors inside the Messages handler, streamed error
frames and the SDK streaming adapters keep the merge base's table.
The dashboard toast reads a status before embedded JSON and titles by Anthropic
type only when the body is an Anthropic error envelope, so other pages keep
their titles.
* test(anthropic): mark the new test variables Final

* fix(proxy): send a real error event when a /v1/messages stream fails
When a stream failed halfway through, the proxy wrote the error as a plain
`data: {"error": ...}` line with no `event:` in front of it. Anthropic clients
pick stream events by that name, so they skip the line and the request looks
like it simply stopped with nothing in it.
Write the failure as an `event: error` frame with Anthropic's own payload, and
take the error type from the status code
* fix(proxy): use the shared Anthropic error mapping for the stream error frame
The first pass added a third copy of the status to error-type table, and it
disagreed with the documented one: 529 came out as `api_error` rather than
`overloaded_error`, and 413 as `invalid_request_error` rather than
`request_too_large`, which hides the two failures a client can actually act on.
Drop that copy and put the frame builder next to the table litellm already
keeps in anthropic_interface/exceptions. The bridged adapter path was building
the same frame inline, so it uses the shared one now too
* fix(proxy): seal a torn SSE frame before the /v1/messages error event
An upstream that drops mid-frame leaves the client inside an open event,
so the error frame that follows is glued onto the torn data line and the
Anthropic SDK raises a JSON decode error instead of an APIStatusError.
Close the open frame with a ping event the SDK skips before writing the
error event, and add the e2e stream-cut edge with Bedrock, Anthropic
boundary, and Anthropic mid-frame legs.
* fix(proxy): keep the SSE tail unchanged on a chunk that is not text
A serializer that hands a dict or model object through as-is has no bytes
the frame tail can learn from, so advance_sse_tail leaves it alone instead
of slicing it.
* fix(proxy): answer a /v1/messages stream that fails before its first byte as a JSON error carrying its status
* test: move the Anthropic error frame tests into tests/unit
* test(e2e): cut the upstream stream only after content has been relayed
* test(e2e): carry split SSE lines across chunks and always tear a data line mid-frame
* test(e2e): find the next data line across a chunk boundary before tearing it
