Subject: [PATCH] feat(ar1-admin): bottone Anteprima PDF wirato a BE
 /admin/ar1-templates/:id/preview-pdf

Rimosso toast 'TODO' dal bottone eye icon in Tab Template. Ora:
  1. chiama Ar1Service.previewTemplatePdf(row.id) (nuovo metodo, ritorna Blob)
  2. crea URL.createObjectURL + window.open('_blank')
  3. revokeObjectURL dopo 60s (cleanup)
  4. toast info iniziale 'Generazione anteprima...' + error toast su fail

Service: +1 metodo previewTemplatePdf(templateId) che torna Promise<Blob>
usando buildHeadersMultipart (nessun Content-Type per risposta binaria).
