Add N8n integration with models, services, and routes
- Introduced N8n and N8nSetting models in both MySQL and PostgreSQL schemas. - Implemented N8nController and N8nService for managing N8n bots. - Created N8nRouter for handling API requests related to N8n. - Added DTOs and validation schemas for N8n integration. - Updated server module and chatbot controller to include N8n functionality. - Configured environment settings for N8n integration.
