feat: Zielgruppen-Verwaltung (Target Groups CRUD + Admin UI)
Backend:
- GET /api/target-groups: Liste mit hierarchischem Kontext (focus_area → training_style → target_group)
- POST /api/target-groups: Create (admin only)
- PUT /api/target-groups/{id}: Update (admin only)
- DELETE /api/target-groups/{id}: Delete (superadmin only) mit CASCADE-Schutz
- Filter: by training_style_id, status
Frontend:
- api.js: listTargetGroups, createTargetGroup, updateTargetGroup, deleteTargetGroup
- AdminCatalogsPage: Neuer Tab "Zielgruppen" (6. Tab)
- Create-Form: training_style_id, name, description, min_age, max_age
- List-View: Hierarchie-Anzeige (Fokusbereich → Stil → Zielgruppe + Altersbereich)
- Inline-Editing mit Stil-Auswahl-Dropdown
- Delete mit Confirmation Dialog
Architektur:
- Hierarchische Beziehung: target_groups.training_style_id → training_styles → focus_areas
- CASCADE-Protection: DELETE verweigert wenn exercise_target_groups Einträge existieren
- Backend liefert enriched data mit training_style_name + focus_area_name
