test(inputs): add service-level test for CDC create field-mapping

InputsService.createCdc builds InputCreateCdcRequest by enumerating
fields (not spreading), so a revert of the destination/iceberg_table_name
mapping lines would not be caught by the existing controller spec, which
only mocks InputsService. Add a unit test at the service boundary that
asserts destination and per-table iceberg_table_name reach the gRPC
request, plus a back-compat case with no destination.

Also mark CdcTableReq.iceberg_table_name as advisory/reserved: the
platform derives the Iceberg table name itself today and does not yet
consume this field.
