fix(test): correct mock targets, method names, ULIDs, and CLI args in M4 smoke suite

- Patch CorrectionService at its module path, not the local-import site
- Use request_correction/execute_correction/analyze_impact (real API)
- Replace invalid 27-char subplan_id values with valid 26-char ULIDs
- Add required --guidance flag to dry-run CLI invocation
- Fix feature file assertions to match actual CLI output

Resolves CI failures in unit_tests (job 4) and coverage (job 6) for
run 645 on PR #441.
