Aborting a missing request is a no-op: return queued/running/cached counts of zero instead of 404. Parity with legacy http server.

📝 Walkthrough

Walkthrough

The deletion endpoint no longer validates request IDs as UUIDs. For a gRPC NOT_FOUND status, it returns zero queued, running, and cached counts. A test checks that deleting an unknown request returns HTTP 200 with those counts.

Request deletion

Layer / File(s)	Summary
Deletion response and test python/cuopt_server/cuopt_server/proxy_webserver.py, python/cuopt_server/cuopt_server/tests/test_grpc_http_proxy.py	The endpoint returns zero queued, running, and cached counts for NOT_FOUND. The test checks that deleting an unknown request returns HTTP 200 with zero counts. The test uses a shared JSON Accept header.

Estimated code review effort: 2 (Simple) | ~7 minutes

Merge Risk: 🔵 Low · up to 2d2d7

The new test can hang if the proxy stops responding, and the proxy API schema still lists a 404 response this route does not return. Both fixes are localized, so the merge risk is low.

- Line 931: Update the response declaration for the proxy DELETE route handled
by deleterequest to omit HTTP 404 while preserving its other validation
responses; do not alter the shared ValidationErrorResponse map, which is also
used by the self-hosted route.

In `@python/cuopt_server/cuopt_server/tests/test_grpc_http_proxy.py`:
- Around line 1198-1200: Add a finite timeout to the requests.delete call in the
test so the request cannot block indefinitely; preserve its URL and headers.

Correct REST semantics -- aborting an already-gone request becomes a 200 no-op instead of a 404, and removing _require_uuid here is safe by the same reasoning already verified on #1987: client.status(id) resolves an unknown/malformed key to NOT_FOUND rather than raising, and _get_job is a plain dict.get, so a non-UUID id flows through cleanly to the same zero-count response. Minimal, surgical diff.

Non-blocking: no test covers a malformed (non-UUID) id on this specific route (only unknown-but-well-formed-UUID is tested). Not concerned it's actually broken given the above, but would be good for symmetry with the other routes' coverage.
