cleanup: remove Helm charts and references from codebase

- Remove infra/helm directory (20 files including charts and values)
- Remove Helm prerequisite checks from deploy.sh and production-deploy.sh
- Remove Helm deployment commands for PostgreSQL, Redis, and Prometheus
- Deployment scripts now suggest systemd services instead of Helm
- Addresses request to remove Helm support
