Correctifs UI workflow — specs + implémentation (8 chantiers) (#6)

Suite à l'arrivée des workflows, correction des régressions UI et améliorations UX mail/modales (reviews Lucile Schnödt, Tristan Schnödtin).

**Specs & décisions :** `docs/superpowers/specs/2026-05-20-workflow-ui-fixes-design.md`
**Plan d'implémentation :** `docs/superpowers/plans/2026-05-21-workflow-ui-fixes.md`

Cette PR contient désormais **les specs ET l'implémentation complète**.

## Chantiers livrés

| # | Chantier | Détail |
|---|----------|--------|
| 2 | Sélecteur de statut filtré par workflow | `statusOptions` dérivé de `project.workflow.statuses`, statut courant conservé s'il est hors workflow |
| 1 | Drag & drop « Mes tâches » | handlers `@dragover/@drop` ; résolution par workflow/catégorie (0→refus, 1→PATCH, ≥2→popover `StatusPickerPopover`) |
| 4 | Couleurs | (a) migration Doctrine remettant les hex classiques sur le workflow Standard ; (b) entêtes kanban teintées via `STATUS_CATEGORY_COLOR` + contraste auto ; (c) couleur par défaut par catégorie dans `WorkflowDrawer` |
| 5 | Suppression du bouton « Lier un mail » | + retrait de `MailPickerModal` et i18n associée |
| 6 | Création de tâche depuis un mail | back : `assigneeId` + `statusId` (défaut = 1er statut du workflow), priorité retirée (TDD) ; front : `MailCreateTaskModal` sur `AppModal` + sélecteurs user/statut |
| 7 | Modale réutilisable | nouveau `components/ui/AppModal.vue` (footer sticky) ; footer de `TaskModal` sorti du form scrollable |
| 3 | Cartes responsive | badges en `flex-wrap` pleine taille (plus aucun débordement) |
| 8 | (dette) Sélecteur de catégorie en `MalioSelect` | la lib supporte les valeurs `string` ; note CLAUDE.md corrigée |

## Vérifications
- Build frontend OK ; PHPUnit **34 tests verts** (nouveau test fonctionnel TDD sur `create-task`).
- Vérif navigateur (Chrome MCP) sur **données prod importées en local** : #2, #3, #4, #5, #6, #7 confirmés.
- Revue de code finale : **APPROVED_WITH_NITS**.

## À noter
- ⚠️ **#1 (D&D)** : le drag & drop HTML5 natif n'est pas auto-testable → **test manuel requis**.
- 🗄️ **#4 (migration)** : `migrations/Version20260521094948.php` s'appliquera en **prod au prochain `make migration-migrate`**.
