## Summary by CodeRabbit

- **New Features**
- Introduced new fields in the `AuthorizedParty` and
`AuthorizedSubParty` types to enhance user representation and
relationships.
- Added a new type `AuthorizedSubParty` to support nested party
structures.

- **Bug Fixes**
- Improved the `GetAuthorizedParties` method to return a more complex
structure, including nested sub-party information.

- **Refactor**
- Updated class structure and inheritance for `AuthorizedParty` and
`AuthorizedSubParty` to facilitate better organization and
relationships.
