fix(sdk): resolve Pydantic deserialization failures from WHMCS API

Remove format: date from all date fields to handle WHMCS returning
"0000-00-00" for unset dates. Simplify oneOf integer/string unions
to type: string to handle WHMCS returning unexpected types. Strip
unused fields from ClientDetailsInfo, ClientDetailsStats, and
InvoiceInfo down to what athena actually consumes, and add
additionalProperties: true throughout to absorb unknown fields
without validation errors. Bump version to 1.0.16.
