LAB-519 - Prepare Registry integration

Moving From VCard Address to Gaia-X Address

This merge request removes the fact that the Address entity is a vcard:Address, making it a Gaia-X entity which gives more freedom to extend it.

New Registration Number Attributes

RegistrationNumber subtypes have evolved to include the attributes currently used by the Gaia-X Clearing House. A TaxID subtype has also been introduced to match the Gaia-X Notary's OpenCorporates TaxID class.
