Fix Guestline + Mews direct scrapers after engine API changes

Browse source 
Both competitor booking engines changed their API contracts, silently
breaking their direct scrapes ~16 days ago (200 responses with empty
bodies, so no exception was ever raised):

- Guestline: the /enhanced availability endpoint now returns a bare []
  for every date. Switch to the base /api/availabilities/{coll}/{hotel}
  endpoint, which returns {"rooms":[...]} with the same room shape.
- Mews: getAvailability now rejects the old body with "Invalid
  EnterpriseId" — it requires enterpriseId + serviceId. getPricing
  additionally requires currencyCode. Capture the enterprise's
  defaultCurrencyCode in _ensure_config and send all three.

Also stop last_scraped_at advancing when a run saves 0 rows, so the
overview no longer reports a phantom-fresh scrape while the per-date
data stays stale — the symptom that surfaced this.

Verified live: Three Ways now yields 41 rows/night, Old Stocks 10.
