# Snippet to merge into server.py (reference for push):
# 1) Replace langchain hack block with:
#    import core.langchain_compat  # noqa: F401
# 2) After grant_search_service import area add:
#    from core.search.grant_search_catalog import apply_search_patches
#    apply_search_patches()
# 3) Include routers:
#    from endpoints.grants_catalog import router as grants_catalog_router
#    from endpoints.grants_admin_import import router as grants_admin_import_router
#    app.include_router(grants_catalog_router)
#    app.include_router(admin_router, prefix="/api/admin")  # grants_admin merged into admin
# 4) lifespan empty DB: await sync_wyszukiwarka_catalog() before sync_grants_to_db
