fix: make health probes use named ports and improve Makefile idempotency

- Change all health probes to use 'port: http' instead of hardcoded 8000
- Makes chart robust to service.port configuration changes
- Update install-all and upgrade-all to use 'helm upgrade --install'
- Ensures batch operations are idempotent and won't fail on re-runs
- Add --create-namespace to upgrade-all for consistency
- Improve overall chart reliability and user experience
