Update Temporal and n8n configurations with latest versions and environment variables

- Update n8n from 1.22.0 to 1.89.2 and change working directory
- Update Temporal from 1.20 to 1.20.5 and configure with environment variables
- Replace Elasticsearch with OpenSearch for Temporal visibility
- Add environment variables for n8n and database configurations
- Improve container restart policies with unless-stopped
- Update documentation with volume setup instructions and troubleshooting
- Add .gitignore entries for mcp executable, config files and .cursor
- Fix volume paths and opensearch port mapping
