Remove all payment-related conversion from the legacy converters and tests.
Add the GetPaymentUseCase as a new dependency to doctrine donation repository, querying the data when writing. There are values in the legacy data that have their own column (outside the data blob)
- payment type
- payment reference code (formerly known as payment reference), table column ueb_code
- donation state (set in updateStatusInformation)
Test with the real implementation of the LegacyDataService to make sure legacy data still gets written.
