- Add 'RDA Pre-servicios por fecha' and 'RDA Pre-servicios por número'
default queries joining PRESSERV_DIAN (ID_PS, PS_PREFIJO, PS_NUMERO)
- Refactor _query_rows: only pass params the query actually uses;
prefix filter works for both PREFIJO and PS_PREFIJO columns
- Add _is_preserv(), _agrupar(), _build_rda() helpers that detect
pre-servicio rows and produce correct prefijo/numero overrides
- All 4 send endpoints (preview, send-one, send, send-direct) now
group by ID_PS for pre-servicio queries and pass correct RDA fields
- RCXC prefix still maps to '00' in the RDA codigoPrefijo
