Refactor DLHD Live Sports Events scraping and storing the data

Reworked the caching logic to handle a missing cache key for "events" type gracefully. Integrated a new DLHD schedule service for improved event metadata and stream handling, leveraging fuzzy matching and IPTV-org data retrieval for enhanced TV channel mappings. Updated scraper configuration, enhanced genre handling, and added support for dynamic event descriptions.
