/**
 * Export XLSX du repertoire clients (M1, spec-back § 4.6).
 *
 * Controller Symfony custom (et non operation API Platform) car il produit un
 * binaire de fichier, pas une representation Hydra. `priority: 1` est
 * OBLIGATOIRE sur la route : sans cela API Platform capterait
 * `/api/clients/export.xlsx` comme l'item `GET /api/clients/{id}.{_format}`
 * (id="export", _format="xlsx") — cf. CLAUDE.md « controller custom sous /api ».
 *
 * Separation des responsabilites :
 *  - le COMMENT (generation du fichier) est delegue au service Shared
 *    {@see SpreadsheetExporterInterface} — generique, reutilisable, sans metier ;
 *  - le QUOI vit ICI : selection des clients (memes filtres que
 *    `GET /api/clients`, via {@see ClientRepositoryInterface::createListQueryBuilder()})
 *    et mapping metier des colonnes.
 *
 * La colonne SIREN n'est ajoutee que si l'utilisateur a la permission
 * `commercial.clients.accounting.view` (gating identique a la lecture).
