fix(ci): standardize Python dependency management across all jobs

- Add requirements.txt with core Python dependencies
- Replace --target installation with setup-python@v4 (official action)
- All jobs now use cache: 'pip' for consistent caching
- Explicit 'pip install -r requirements.txt' or specific packages
- Fixes 'No module named pytest' in ci-storage job
- Fixes 'No file matched to requirements.txt' in Setup Python step
- All jobs: pyyaml, requests, openpyxl, pytest, psycopg installed globally
- Removes PYTHONPATH env vars (no longer needed with proper setup-python)
