feat(crm): módulo Tarifario — modelos, CRUD, import Excel y motor de costeo

- Tablas rate_sheets/lanes/breaks/charges (esquema crm) + migración con down().
- Catálogos nuevos: modo_tarifario, unidad_tarifa, concepto_cargo.
- CRUD de tarifarios y rutas; descarga de plantilla Excel por modo; import con
  vista previa y validación; alta directa desde Excel.
- Motor de costeo /rate-quote: aéreo (peso facturable + quiebres + optimización),
  marítimo FCL (por contenedor), LCL (W/M) y terrestre; suma cargos adicionales.
