"""E2E of the enrichment across REAL HTTP: the real Agent worker (real Firebird COPY) <-> the real Hub container (dev PostgreSQL, real datasets, real providers).

    docker compose up -d --build fiscal-hub   # Hub at http://localhost:8000
    python scripts/enrichment_local_hub_e2e.py

Registers a throw-away dev Agent (AGENT_DEV_TOKEN), flips its per-installation features straight in the dev database (the panel route is covered by tests), seeds the KB of the dev Hub with a VERIFIED NCM for
one test GTIN (two independent provider families), then walks: DISABLED -> DRY_RUN -> ENABLED -> DISABLED, an unknown GTIN (real providers, internet) and an invalid GTIN (no provider call).
Writes go ONLY to scratch_rtc_e2e/TESTESOFICIAIS_RTC_COPY.FDB (guarded by rtc_copy_write_e2e.guard). The dev database receives test rows only.
