test(integration): stop GET /__observations from draining the upstream log (#47256) 
* test(integration): stop GET /__observations from draining the upstream log

GET /__observations used to empty the queue, so a second read in a test
saw nothing and a "never reached upstream" check could pass whether or not
the request was forwarded. GET now returns every request since the last
reset and DELETE /__observations is the reset. An autouse fixture resets
the worker upstream before each test, which also covers tests that read
without the gateway fixture.

Discarded reads used as resets become DELETEs, helpers that accumulated
drained reads now read one snapshot, and tests with several phases reset
between them. The three vacuous negative checks (rag allowlist, guardrail
opt-out chaos, xAI batch output) now assert the absence on the same read
that shows a request which did reach the upstream.

* style(integration): space the observations unit test like its neighbours
