v1.4.1: MAJOR FIX - Moved from Redis to Valkey, added migration service to support, Utilizing Hi-Fi API 2.7 with ISRC search, preserve local item json objects, add a quality fallback, added "transcoding" support that just reduces the fetched quality, while still downloading at the quality set in the .env, introduced real-time download visualizer on web-ui (not complete), move some stuff from json to redis, better retry logic, configurable timeouts per provider
