"""Apify enrichment client — runs the owner's own actors and fetches results.

Actors (defaults are the account's own published actors, configurable via env):
  - sitcod3.lab/fdn-google-map-master-scraper   (Google Maps → companies)
  - sitcod3.lab/linkedin-company-email-scraper  (LinkedIn → employees + emails)

Both sync (run-sync-get-dataset-items, capped) and async (run + poll) modes
are supported. Output items are schema-flexible: the normalizer probes common
Google Maps / LinkedIn export field names case-insensitively.
