feat: deployment security hardening

- Redis: add password authentication (requirepass), update healthcheck
- PostgreSQL: replace hardcoded password with env variable
- Docker Compose: remove obsolete version field, use env vars for credentials
- Add .env.production.example template with strong password placeholders
- Update all .env files with new credentials and ports

.env.production.example
