[docs] fix swag annotations

[capcom6]

Greptile Summary

The PR corrects Swagger annotations for message-list query parameters and updates the generated OpenAPI document.

• Separates the limit and offset parameter annotations.
• Uses the processing-state type to generate the complete state enum.
• Corrects OpenAPI constraint keywords for device IDs and pagination limits.

Confidence Score: 5/5

The PR appears safe to merge.

No blocking failure remains; the previously reported concatenated parameter annotation is fixed in the current code and reflected correctly in the generated OpenAPI output.
