feat: implementar CRUD completo para exchange_rate, packages y seal

Backend:
- Corregir tipos datetime en exchange_rate (dto.py, models.py)
- Agregar datetime import en packages dto.py
- Corregir orden de parámetros en seal services.py
- Actualizar router.py con nuevas rutas

Frontend:
- Crear API clients para exchange-rate, packages y seal
- Implementar componentes de tabla con renderComponent
- Crear diálogos de crear/editar para cada módulo
- Implementar data-table-actions con manejo interno de diálogos
- Agregar páginas completas con filtros e infinite scroll
- Actualizar sidebar con nuevos módulos

Características:
