bruno 38f39a10ae feat: tri, filtre, recherche et export CSV dans la visionneuse XLSX #153
A13 (affichage seul, le classeur n'est jamais réécrit) : clic sur un
en-tête pour trier la colonne (asc/desc, numérique si toutes les valeurs
le sont, localeCompare fr sinon — les cellules modifiées suivent leur
ligne) ; l'unique champ de recherche filtre les lignes ET surligne les
occurrences (marque <mark>, navigation ↑/↓/Entrée, compteur i18n,
insensible à la casse par défaut, bouton Aa) ; bouton « Réinitialiser »
qui re-rend le fichier (vérité serveur) ; export CSV de la feuille
visible (BOM UTF-8, échappement ;/" et retrait des ombres de valeurs
calculées).

Vérifié : xlsx-viewer.test.mjs 30/30 (5 nouveaux) + contre-preuves
(tri neutralisé -> 1 échec, filtre neutralisé -> 1 échec), validate-imports,
i18n parity (xlsx.find_*, xlsx.sort_*, xlsx.csv_export).

/**
* ObsiGate — JSDOM integration tests for the Excel viewer (ROADMAP #153 P0).
*
* Loads the real viewer.js module and drives renderXlsxViewer():
* - A1 : `xlsx_lossy_features` renders a warning banner; a save on such a
* workbook gets 409 `xlsx_lossy_content`, asks for confirmation and
* retries with `force: true` (or gives up when refused);
* - A4 : the f(x) toggle flips `allow_formula` in the save payload.
* - A8 : a sheet bigger than the render caps shows the truncation notice.
* - A9bis : the tail of a truncated sheet is fetched window by window from
* GET …/xlsx/sheet (scroll sentinel + click), and the appended rows are
* editable like the initial ones.
* - A7 : formula bar mirrors the active cell; arrows/Tab navigate; editing
* from the bar marks the cell dirty; Escape reverts.
* - A13 : header click sorts the rendered rows, the filter hides rows, the
* find highlights matches, CSV export downloads the visible sheet.
*
* Usage: node tests/frontend/xlsx-viewer.test.mjs
