test(config): lock in .gittensory.yml import fidelity for config-generator (#2212) (#4640)

Locks in that the config-generator's 'import existing .gittensory.yml into the form' reads an operator's
file back through parseFocusManifestContent with a multi-section config's values (gate + review +
settings.autonomy) round-tripping faithfully — not merely parsing without warnings. Test-only, single file.

Closes #2212
