fix: positionnement des cartes selon les labels et mise à jour après édition

- create_issue: utilise _issue_column() au lieu de hardcoder 'Backlog'
- update_issue_api: recalcule la colonne après changement de labels
- update_issue_api: utilise l'endpoint PUT /labels au lieu de PATCH (Gitea ignore labels dans PATCH)
- webhooks: utilise _issue_column() pour 'opened'/'reopened'
- saveIssueEdit: rafraîchit le board (HTMX) après édition au lieu de rouvrir la modale
- update_issue_labels: corrigé pour utiliser PUT /issues/{id}/labels (liste d'entiers)
