feat: Training Types → Focus Area Hierarchie

Migration 013:
- Adds focus_area_id to training_types (context-specific types)
- Migrates existing data to Karate focus area
- Seeds focus-area-specific training types:
  * Karate: Dan-Vorbereitung
  * Gewaltschutz: Präventivkurse, Intensivtraining, Spezialkurse
  * Fitness: Gesundheitssport, Funktionelles Training
- Updates unique constraint to (name, focus_area_id)

Backend (catalogs.py):
- list_training_types: Added focus_area_id filter, LEFT JOIN focus_areas
- create_training_type: Added focus_area_id parameter
- update_training_type: Added focus_area_id parameter
- Enriched responses with focus_area_name and focus_area_icon

Frontend (AdminCatalogsPage):
- Added Fokusbereich dropdown to create form
- Added Fokusbereich dropdown to edit form
- Display shows focus_area_icon and focus_area_name
- Training types now context-specific to focus areas
