Returns one page of 30 in AlohaCamp's recommended order; pass a property `slug` to alohacamp_property for details and exact per-unit prices. Fetched live from alohacamp.com (typically 1–2 s via direct fetch; a few seconds more right after AlohaCamp deploys, or when it falls back to an unblocker). Result shape: { source, fetchedAt, query, search_url, resolved_location, total_count, page, total_pages, count, nights, properties: [...], note? } — the list key is `properties`; `total_count` counts matches across all pages (use `page` for more). Each property: { id, slug, name, url, city, region, country, lat, lng, property_types, units, max_guests, units_for_party, price_per_night, club_price_per_night, total_price_estimate, currency, rating, review_count, image, photos_count, guests_choice, is_new, only_on_alohacamp, free_cancellation, meals_available, meals_included, extra_fees }. Prices are numbers in PLN: `price_per_night` is the lowest nightly price for the whole party (with dates, the average over those nights; `units_for_party` > 1 means it covers several units), `total_price_estimate` = price_per_night × nights (null without dates; fees in `extra_fees` are paid on top), `club_price_per_night` is a lower members-only price when there is one. `rating` is 0–5 (null without reviews).
