refactor: Update content_attributes in ChatwootService

This commit refactors the code in ChatwootService to update the content_attributes when replyToIds are present. Instead of directly spreading the replyToIds object, the code now converts it to a JSON string and appends it to the data object.

Refactor the code to improve readability and maintainability.
