fix flaky test #2145

2026/01/14 14:12:35 [ocwrapper] OpenCloud server is ready to accept requests
{"level":"error","service":"proxy","error":"failed to verify access token: 405 Method Not Allowed: ","authenticator":"oidc","path":"/graph/v1.0/use/admin","user_agent":"GuzzleHttp/7","client.address":"","network.peer.address":"172.22.0.3","network.peer.port":"51842","time":"2026-01-14T14:12:35Z","message":"failed to authenticate the request"}

This typo prevented us from correctly clearing all tokens and obtaining a new token.

Please rebase to get the starlark fix: #2149

Looks good otherwise.
