Update API Documentation to Include Missing Fax Status Codes

[dxdc]

Several fax status codes are reported by the API, but they do not appear in the API documentation.

For example:

• failed_call_rejected
• failed_origination_unknown
• failed_zero_page_transmitted

There may be other status codes that are not currently documented. It would be beneficial to have a more comprehensive list of error codes along with their human-readable definitions, similar to those provided in the web console or via the getFax method in the API, which includes more descriptive definitions.

This enhancement would improve the clarity and usability of the API for developers, ensuring they have the necessary information to handle various fax statuses effectively.

Thank you!
