feat(templates): exponer importación desde otro proyecto y desde CSV/Excel

El TemplateManager ya implementaba ambos flujos pero la vista no los exponía.
Añadidos a la cabecera los botones "Importar de proyecto" e "Importar CSV/Excel" y
sus modales:
- CSV/Excel: nombre + fichero, vista previa de campos detectados, crear; con enlace
  para descargar CSV de ejemplo.
- Otro proyecto: selección de proyecto accesible + checklist de plantillas a importar.

Tests: TemplateImportTest (importar de proyecto y desde CSV). Suite 81 passing.
