test(musty_leopard): cover customer chat/messages cost + streaming paths (#34164)
* test(e2e): cover customer chat/messages cost + streaming paths

Fills five uncovered P0 registry cells matching the customer's confirmed stack
(OpenAI SDK, Bedrock, /v1/messages) and their per-request cost dependency:
- /v1/messages logs cost that matches the x-litellm-response-cost header (LIT-4076)
- OpenAI /chat/completions streams real content, and a non-streamed call is costed
- Bedrock Converse /chat/completions returns real content non-streamed and streamed

The streaming checks aggregate delta content and parse every chunk as JSON, so a
clean-but-empty stream or a truncated chunk fails instead of passing on a bare 200.

* test(e2e): add tool-use coverage for openai, bedrock converse, anthropic responses

Function-calling regression guards on the paths the customer's agentic SDK usage
exercises: OpenAI and Bedrock Converse /chat/completions, and Anthropic
/v1/responses. The model is forced to call a weather tool and the test asserts the
returned tool call names the function and carries JSON-parseable arguments with the
expected field, so a dropped tool_call or malformed argument JSON fails instead of
passing on a bare 200. Adds a minimal tool_calls field to the response OutMessage.

* test(e2e): cover bedrock converse responses + thinking

Adds llm.responses.bedrock_converse.basic/tool_use and
llm.chat_completions.bedrock_converse.thinking. The thinking test enables extended
thinking and requires reasoning_content plus a real answer, so a path that drops
the reasoning block fails rather than passing.

* test(e2e): cover bedrock embeddings + openai structured output and reasoning

Bedrock Titan embeddings return a real vector; OpenAI structured output must yield
schema-conforming JSON with the correct extracted values (age==42, not just valid
JSON); an OpenAI reasoning call must report reasoning tokens, so a non-reasoning
fallback fails. Adds response_format to ChatBody and reasoning-token details to Usage.

* test(e2e): cover vision + streaming tool calls on openai and bedrock converse

Vision on both providers must describe the image (not just 200); the streamed
OpenAI tool call is reassembled from its fragments and its argument JSON parsed, so
a stream that never completes the call or splits its JSON fails. Extends ChatMessage
content to a typed text/image union.

* test(e2e): cover openai prompt caching hit on repeated large prefix

A repeated large-prefix prompt must report cached prompt tokens on the second call,
so a cache regression that stops reusing the prefix (and silently re-bills full
input) fails here.

* test(e2e): cover openai audio speech + bedrock rerank and image generation

Marks the OpenAI TTS cell and adds Bedrock Titan rerank (top_n honored, scored) and
Bedrock Titan image generation (returns b64/url), the customer's non-chat AWS
surfaces.

* test(e2e): cover end-user (customer) create persistence

mgmt.end_user.new.happy_path: create an end-user via /customer/new and confirm
/customer/info reports it, the end-user-identity surface the customer relies on for
per-customer controls. Adds customer models + management-client methods.

* test(e2e): enforce key model allow-list on the passthrough route

other.auth.passthrough.model_allowlist_enforced: a key scoped to gemini must be
denied a claude call through the anthropic passthrough route (403), so custom-auth
scoping is not bypassable by going through passthrough instead of /chat/completions.

* test(e2e): address Greptile - assert stream data events, correlate messages spend by key

- streaming: assert len(stream_events) > 1 instead of chunks > 1, since chunks
  counts the terminal data: [DONE] marker and would pass a single content event
- messages cost: correlate the spend row by the unique scoped key rather than the
  Anthropic response id, which need not equal the proxy spend-log request_id
