test(util/git): port interactive Bitbucket OAuth runCommand test

Implement the four privateBitbucketWithOauthProvider cases that were
stubbed as an ignored todo!(). Extend IOStub with per-question
askAndHideAnswer responses and auth pre-seeding so the stateful OAuth
flow can be driven without willReturnCallback, and inject a mock
HttpDownloader plus no-op config sources to mirror PHPUnit's Config mock.
