refactor: remove EvolutionBot chatbot integration

Remove the EvolutionBot chatbot integration as it is no longer needed.
The project now supports only external chatbot integrations: Chatwoot, Typebot, OpenAI, Dify, Flowise, N8N, and EvoAI.

Changes:
- Deleted EvolutionBot directory with all files (controller, service, router, dto, schema)
- Removed EvolutionBot models from Prisma schemas (postgresql and mysql)
- Updated ChatbotController to remove evolutionBotController.emit() call
- Updated ChatbotRouter to remove EvolutionBot route
- Cleaned up imports and exports in server.module.ts
- Updated documentation (CLAUDE.md, AGENTS.md)

Note: Prisma migrations will be created separately to drop EvolutionBot and EvolutionBotSetting tables from the database.
