MLPAB-1194: Remove unused properties from Types

[acsauk]

Purpose

This is mostly removing props from the details a certificate provider enters that we no longer ask for. As we were relying on the names being available on CertificateProviderProvided I've fallen back on getting these from the LPA itself.

Fixes MLPAB-1194
