- Remove hardcoded database credentials from all scripts - Remove hardcoded Legacy API tokens from backend scripts - Remove hardcoded MQTT credentials from mqtt-test.js - Update backend/.env.example with DB_HOST, DB_USER, DB_PASSWORD, DB_NAME - Update backend/.env.example with LEGACY_API_TOKEN and MQTT credentials - Add dotenv config to all scripts requiring credentials - Create comprehensive documentation: - scripts/README.md - Root scripts usage - backend/scripts/README.md - Backend scripts documentation - MQTT_TESTING.md - MQTT testing guide - SECURITY_CREDENTIALS_CLEANUP.md - Security changes summary All scripts now read credentials from backend/.env instead of hardcoded values. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
