Fix incomplete Portal intent documentation and add validation

Update PHPDoc to include missing intent values (certificate_renewal,
domain_verification) and add runtime validation for $intent parameter
to provide better error messages before API calls. Includes test
coverage for all intent values and invalid intent handling.

Fixes #295
