Add function to retrieve company address as JSON and update invoice procedures

- Created a new function `fds__getCompanyAddressJson` to return a company's postal address as a structured JSON object.
- Modified stored procedures `fds__createInvoice`, `fds__setInvoice`, and `fds__prepInvoice` to include a new parameter `@SendToAddressJson` for handling the address data.
- Updated the invoice table and user-defined types to accommodate the new `SendToAddressJson` field.
- Ensured that the address data is properly retrieved and stored in the invoice records.
