feat(kafka): add Kafka integration for event streaming

- Introduced Kafka support in the Evolution API, allowing for real-time event streaming and processing.
- Updated environment configuration to include Kafka-related variables.
- Added KafkaController and KafkaRouter for managing Kafka events.
- Enhanced event management to support Kafka alongside existing integrations.
- Updated database schemas and migrations for Kafka integration in both MySQL and PostgreSQL.
- Documented Kafka integration in the README file.
