fix: update logging and message handling in EvoaiService

This commit modifies the logging messages in the `EvoaiService` to use the correct service name "EvoAI" instead of "Dify" for better clarity. Additionally, it refines the message handling logic by changing the way message IDs are generated and updating the payload structure sent to the API. The extraction of the message from the response artifacts has also been improved to ensure that the correct message is retrieved from the response data.

Changes include:
- Updated logging statements to reflect the correct service name.
- Changed the message ID generation to use a shorter UUID substring.
- Adjusted the payload structure to include `contextId` and `messageId`.
- Enhanced message extraction logic from the response artifacts.

These changes enhance the clarity of logs and improve the robustness of message handling in the service.
