Add Python-based entrypoint.sh that authenticates with Infisical via
universal-auth, fetches secrets, and exports them as env vars before
starting uvicorn. Secrets like MOLLIE_API_KEY, PRODIGI_API_KEY,
PRINTFUL_API_TOKEN, JWT_SECRET, GEMINI_API_KEY, and FLOW_* vars are
now pulled from Infisical instead of being passed through docker-compose.
Gracefully degrades: if no INFISICAL_CLIENT_ID/SECRET are set or if
the fetch fails, the container starts with whatever env vars exist.
