scripts/export_openapi.py
FastAPI app'ten OpenAPI JSON cikar, packages/types/openapi.json'a yaz.

Bu, TS type generation icin referans dokuman saglar (TS tipleri zaten
elle yazili — packages/types/src altinda — ama OpenAPI'yi de sakliyoruz ki
otomatik client uretmek isteyen olursa kullanabilsin).

Kullanim:
    cd services/backend
