[PR] test(metrics): pin the metrics source connection defaults [rocketmq-dashboard]

["zjncs (via GitHub)" <gi...@apache.org>]

URL: https://github.com/apache/rocketmq-dashboard/pull/5751

   ### What
   
   `MetricsSourceSettings` — the resolved connection settings every Prometheus-compatible backend is queried through — had no test. This adds `MetricsSourceSettingsTest` with 3 tests.
   
   ### What is pinned
   
   - **the builder defaults are the operational budget**: 3s connect / 10s read, PROMETHEUS backend, no auth;
   - every supplied value overrides its default;
   - **the query path is the backend's own, delegated by type** — a Victoria Metrics source must not be queried on the Prometheus path.
   
   ### Verification
   
   - New tests on unmodified code: **3/3 green**, checkstyle clean (`mvn test -Dtest=MetricsSourceSettingsTest`).
   - Discriminating mutations on `MetricsSourceSettings`, build result verified red each time:
     1. the connect timeout default relaxed from 3s to 30s — red;
     2. the query path hardcoded to the Prometheus path instead of delegated — red;
     3. the default auth type changed from none to basic — red.
   - Restored: 3/3 green. Test-only change; no product code touched.
