fix(tests): add missing mocks for getDefaultRemote and loadRepoConfig

The orchestrator test mocked @archon/git without getDefaultRemote and
../config/config-loader without loadRepoConfig, causing CI failures.
Also update syncWorkspace assertions to use objectContaining so they
don't break when additional options (like remote) are passed.
