lukaszraczylo 0f78b98192 test(yaegi-check): verify usage-provenance metrics under the interpreter ...

Add a provenance-est provider whose upstream answers with no "usage"
field at all, driving a real, non-streaming chat completion against it
under Yaegi. exerciseUsageProvenance then parses GET /metrics with the
real Prometheus TextParser and confirms both new families
(llmgateway_usage_provenance_requests_total and
-_tokens_total) render as COUNTER type with a distinct "estimated"
series for this provider and a distinct "reported" series for openai's
own already-driven traffic, then confirms GET /admin/api/overview
surfaces the identical estimated observation and never leaks a
"reported" key into the compact admin summary.

Run at the end of run(), after every other probe that already reads
/metrics or /admin/api/overview, so it never perturbs a counter an
earlier probe asserted on.
