weichen lai updated YUNIKORN-3337:
----------------------------------
Description:
When running unit tests in `pkg/webservice` locally (e.g., under WSL via `make
test`), tests can fail with `connection refused` errors:
{code:java}
2026-07-26T10:09:29.611+0800 INFO core.rest
webservice/webservice.go:74 web-app started {"port": 9080}
--- FAIL: Test_RedirectDebugHandler (0.00s)
--- FAIL: Test_RedirectDebugHandler/statedump (0.00s)

{code}
This happens because WebService.StartWebApp() launches
httpServer.ListenAndServe() asynchronously in a goroutine and returns
immediately. Under local environments like WSL with slight CPU scheduling or
socket binding delays, test cases issue HTTP requests in less than 1 ms
(0.00s), attempting to connect before the OS finishes binding port 9080.
