feat(scraper): Refactor scraper for detailed property fetching

Implements a two-pass scraping system to visit each property's detail page, enabling the extraction of more accurate data like coordinates and BER ratings.
This change significantly improves the scraper's robustness by using multiple fallback selectors and adds support for parsing multi-unit developments.
Also includes build script fixes and a version bump.
