fix(onboarding): remove CLI fast path from _provider_oauth_authenticated — fixes 4 test failures

The hermes_cli fast path ignored hermes_home, returning True from real system auth for OAuth providers. Removed — auth now scoped to hermes_home/auth.json only. 1423 passed, 0 failed.

+### Fixed
+- **`_provider_oauth_authenticated()` now respects the `hermes_home` parameter** — the function had a CLI fast path (`hermes_cli.auth.get_auth_status()`) that ignored the caller-supplied `hermes_home` and read from the real system home. On machines where `openai-codex` (or another OAuth provider) was genuinely authenticated, this caused three test assertions to return `True` instead of `False`, regardless of the isolated `tmp_path` the test passed in. Removed the CLI fast path; the function now reads exclusively from `hermes_home/auth.json`, which is both the correct scoped behavior and what the docstring described. No functional change for production (the auth.json path was already the complete fallback). (Fixes pre-existing test_sprint34 failures)
