feat(export): UI unificada de Excel + PDF en los 4 módulos

- Nuevos assets compartidos /assets/donna-export.{css,js}: botón
  "Exportar ▾" + menú dropdown Excel/PDF y helpers DonnaExport.toExcel
  / .toPDF / .attach / .buttonHtml
- escrituras: refactor de exportExcel/exportPDF para usar el módulo
  compartido (sin cambio de comportamiento)
- tramites: nuevo botón en la toolbar de cada tab (adm/corp/mig/lit),
  exporta los rows filtrados de ese tab; PDF excluye Involucrados
- calendario: nuevo botón al final de la toolbar, exporta visibleEvents()
  (respeta chips de origen y búsqueda)
- horas: reemplaza CSV server-side por XLSX client-side + agrega PDF;
  removida la acción ?action=export del api.php
