fix(caching): never store or serve a chat completion with no choices (#44709)
* fix(caching): never store or serve a chat completion with no choices

A provider response with empty choices was written to the response cache and served on every identical request until the TTL ended, with no provider call in between. The cache now skips storing such a response and treats an already stored one as a miss, so the next request goes back to the provider and its answer replaces the entry.

* fix(caching): skip responses with no output on the Responses API and Anthropic Messages too

* fix(caching): skip streams and stored entries that carry no output

A chat or text completion stream whose chunks carried no choice is closed
by the stream wrapper with one empty choice of its own, so the assembled
response passed the choices check and was cached. The assembled stream is
now judged on its content: a stream with no text, tool call, or other
output in any choice is never stored, on the async and sync writers alike.
The Responses API stream writer and the Anthropic Messages stream writer
apply the same no-output check before storing.

A stored entry with no output read through the worker memory tier is now
evicted from that tier on the miss, so the next read reaches Redis where
the refill lands; the text completion and messages writers only write to
Redis, and the memory copy otherwise kept missing until its own TTL.

* test(integration): response cache cells for answers without output

Deterministic cells for the response cache on every unified endpoint,
streamed and not, through the OpenAI and Anthropic SDKs and raw httpx,
plus the sync SDK paths, stale entries, malformed answers, per-request
TTLs, cache delete, and chaos (Redis stopped or paused mid burst, a
worker killed, in-memory cache mode). The scripted upstream counts only
POSTs as deployment calls, since the proxy's boot-time GET /v1/models
discovery of a config deployment is not one.

* test(caching): pin the stored entry timestamp in the worker-copy test

* test(integration): drop the restating comments from the chaos cells

* test(integration): close the breaker on the first call after the Redis restart
