feat: TUI-Screens für Inventar und Produktion + API-Client Typ-Migration

Neue TUI-Features:
- Inventar: Lageorte auflisten, anlegen, bearbeiten, (de-)aktivieren
- Produktion: Rezepte auflisten, anlegen, Detail-Ansicht
- Navigation erweitert (Hauptmenü, Routing)

API-Client auf generierte OpenAPI-Typen umgestellt:
- 6 neue Alias-Dateien in @effigenix/types (supplier, category, article,
  customer, inventory, production)
- api-client Re-Exports direkt von @effigenix/types statt via Resources
- Backend: @Schema(requiredProperties) auf 16 Response-Records
- Backend: OpenApiCustomizer für application-layer DTOs (UserDTO, RoleDTO)

Hinweis: Backend-Endpoints für GET /api/recipes und
GET /api/inventory/storage-locations/{id} fehlen noch (separate Issues).
