feat(evoai): add EvoAI integration with models, services, and routes
- Introduced Evoai and EvoaiSetting models in both MySQL and PostgreSQL schemas. - Implemented EvoaiController and EvoaiService for managing EvoAI bots. - Created EvoaiRouter for handling API requests related to EvoAI. - Added DTOs and validation schemas for EvoAI integration. - Updated server module and chatbot controller to include EvoAI functionality. - Configured environment settings for EvoAI integration.
