- Join EMPRESA table in all RDA queries to get CODCONTRATO (TNS contract code)
- Use EMPRESA.CODCONTRATO as numeroContrato instead of raw NIT_EMPRESA
- Especialidad always uses default_especialidad (ignore Firebird COD_ESPECIALIDAD)
- sucursal defaults to '00' (not empty) in config and endpoints
- Fix config template label: especialidad default is TNS code not Firebird code

- terceros/transaccion: return clear error when required params (doc_num, num_factura) are missing instead of passing empty dict to Firebird causing Column unknown error
- transaccion: remove prefijo from 'por factura' query; parse num_factura as int when digit
- automation: add /preview endpoint to show patient/reception counts before sending; update UI with preview step and disabled run button until preview loads
- config: add TNS credentials section (tns_empresa, tns_usuario, tns_password, api_sucursal) with test-connection button
- config: add POST /config/test-tns endpoint
