"""Fusiona bloques csv_upload en messages/en.json y messages/es.json y vuelca a src/lib/i18n/csv-upload-messages.*.json.

La fuente de verdad del copy CSV es `messages/{en,es}.json` (alineado con sidebar, dashboard, facturas).
Si editas solo esos JSON, sincroniza con:
  node -e "const fs=require('fs'),p=require('path'),r='.../frontend';for(const l of['en','es']){const j=JSON.parse(fs.readFileSync(p.join(r,'messages',l+'.json'),'utf8'));fs.writeFileSync(p.join(r,'src/lib/i18n','csv-upload-messages.'+l+'.json'),JSON.stringify(j.csv_upload,null,'\\t')+'\\n')}"
