feat: Implementar subida avanzada de expedientes con compresión automática

- ✨ Agregar selección múltiple de carpetas con validación de nomenclatura
- ✨ Implementar compresión automática de carpetas usando JSZip
- ✨ Permitir selección múltiple de archivos ZIP y RAR
- 🎨 Mejorar UI del modal con scroll y gestión de archivos individual
- 🔧 Agregar barras de progreso para compresión y subida
- 🔧 Corregir endpoint a bulk-create y formato FormData
- 🔧 Resolver warnings de React con webkitdirectory
- 📦 Instalar JSZip como dependencia

Funcionalidades nuevas:
- Modal responsivo con altura máxima y scroll interno
- Compresión automática de carpetas antes de envío
- Interfaz consistente para carpetas, ZIP y RAR
- Eliminar archivos/carpetas individualmente
- Contador visual de archivos seleccionados
- Validación flexible de nomenclatura de expedientes
