Fix unguess post watcher body

[Kariamos]

This pull request primarily improves error handling and data validation in the Unguess class and the PostDossiers route. The main changes include providing more detailed error information for failed API calls, ensuring robust parsing of error responses, and validating user IDs before returning them. These updates help with debugging and prevent invalid data from propagating through the system.

Improved error handling in API requests

• Enhanced error handling in Unguess.ts for authentication and POST requests: now, when a request fails, the thrown error includes the HTTP status, status text, and a parsed error body (if available), making debugging easier. [1] [2]

Data validation and robustness

• In the PostDossiers route, user IDs returned from retrieveProjectAndWorkspaceUsers are now filtered to ensure they are positive integers, preventing invalid IDs from being included. If no valid IDs are found, the function returns undefined.
• The join and selection logic in retrieveProjectAndWorkspaceUsers was updated to use a direct string reference for customer_id, improving query clarity and correctness.

Minor improvements

• The campaign ID in the watcher API call is now explicitly converted to a string to avoid potential type issues.
• Added AxiosError import in index.ts for potential future error handling enhancements.
