fix(vault): give test requests a timeout and a name

[LKSNDRTMLKV]

Addresses the diagnosable half of #336. It does not fix the stall — it makes the next one say what it was waiting for, which the previous two did not.

What was wrong

TestClient built reqwest::Client::new(), and reqwest sets no request timeout by default. Every call then ended .expect("HTTP POST failed"), which names neither the path nor the cause.

So a request the server never answers parks until nextest kills the test at 120 seconds: no assertion failure, no panic, no indication of which of a dozen calls was waiting, or for what.

publish_serve_cycle::published_passport_is_served_as_the_payload_its_proof_signed has now failed CI exactly that way twice today — run 35048585684 on #321 and run 35055349549 on #318 — and both runs produced the same non-information. Each cost a full ~11-minute integration cycle, and the integration tier is a required check under strict-up-to-date, so every open PR pays for it.

Both times it was the last test to finish, which is consistent with a hang rather than slowness: scripts/slow-test-check.sh runs a 10-second budget and this test is not on the allowlist, so on every passing run it completes inside ten seconds.

The change

• a 30-second request timeout, chosen to sit between the two numbers that matter — far above anything a local container needs, so it never fires on a slow machine, and far below the 120-second harness ceiling, so a stall is reported as a timed-out request against a named URL rather than as a dead test;
• every request panics with its method, its URL and the cause, and says explicitly when the server accepted the request and never answered — which is a different fault from a refused connection and reqwest's Display does not make the distinction obvious.

What is deliberately not in this PR

The root cause. #336 stays open. The candidates are in it, and the reason they are still candidates is that neither failing run produced evidence — which is the thing this PR changes.

The wider surface. dpp-node/tests/smoke.rs builds a bare reqwest::Client::new() in ten places with the same property. Worth doing, in its own change: this one is scoped to the helper the flaking test actually uses.

just check green — 1224 tests.

Summary by CodeRabbit

📝 Walkthrough

Walkthrough

TestClient now uses a 30-second request timeout. Its request helpers panic with the method, URL, original error, and timeout-specific context. The changelog records that this improves diagnostics but does not resolve the underlying stall.

Timed-out integration tests can report a server-side stall when the request never reached the server, misdirecting diagnosis. Use neutral timeout wording before merge.

reqwest 0.13 ClientBuilder timeout is_timeout source error construction connect timeout official docs

💡 Result:

<search_synthesis>
In reqwest 0.13, you can manage timeouts during client construction using the ClientBuilder struct [1][2]. Timeout Configuration: - connect_timeout(Duration): Sets a timeout for the connection phase specifically [1][3]. - timeout(Duration): Sets a global timeout that applies from the start of the request until the response body has been fully received [3]. - Note: By default, the async Client has no timeout, whereas the blocking client defaults to 30 seconds [4]. These configurations require a runtime, typically Tokio, with timers enabled [3]. Error Handling: - To programmatically determine if an error is caused by a timeout, you can use the is_timeout method on the reqwest::Error type [5][6]. - In reqwest 0.13, this method has been refined to explicitly check for underlying hyper::Error timeout variants and IO-related timeout errors, ensuring better accuracy compared to previous versions [5][7][8]. Under the hood, the ClientBuilder configures these timeouts by wrapping the underlying connector service in a Tower TimeoutLayer [1][9]. If a timeout occurs, the layer emits an error that is eventually surfaced through the request future [9]. If you encounter situations where a timeout appears to be ignored (hanging), ensure the timeout is applied at the appropriate level (e.g., connect_timeout vs. request-level timeout) and that your environment is not subject to OS-level networking behavior that masks timeout signals [10].

Do not infer server receipt from reqwest::Error::is_timeout().

TestClient uses reqwest 0.13.4 and sets ClientBuilder::timeout(REQUEST_TIMEOUT). This timeout covers connection establishment through response-body completion. Therefore, timeout_hint can receive a timeout before the server accepts the request. Replace the server-receipt wording and adjacent documentation with a neutral message, such as " (request timed out before completion)". Update the corresponding CHANGELOG.md text.
