fix: SyntaxError Alpine.js — 'for' inline dans @click remplacé par clearSelection()

- @click='for(var k in selectedIds)...' causait SyntaxError: Unexpected token 'for'
- Cette erreur empêchait l'exécution de TOUT Alpine.data('wsInit', ...)
- Résultat: toutes les variables Alpine 'not defined' (cascade de 80+ erreurs)
- Fix: méthode clearSelection() appelée depuis @click, plus robuste et réactive
