feat: integración completa con API TNS v2

- api_client: agrega get_tns_token() — login en /v2/Acceso/Login y retorna JWT
- json_generator: campos en camelCase según swagger v2; agrega nomRegTri y
  email placeholder cuando el paciente no tiene correo
- terceros/transaccion routes: obtienen token TNS antes de cada envío,
  usan endpoints /v2/tablas/Tercero/Crear y /v2/rda/RdaPaciente/Insertar
- config: agrega tns_empresa, tns_usuario, tns_password
