Refactor: repo hygiene, shared utils, focused tests, and CI improvements

- Remove dead imports/duplication from Google2xls.py and social.py
- Centralize shared logic in review_workflow_utils.py
- Add focused posting-flow tests in tests/test_social.py (all pass)
- Update .gitignore for secrets and local artifacts
- Trim requirements.txt to direct deps
- Improve CI: compile all scripts, run focused tests
- Prep repo for clean commit (no secrets, no local artifacts)
