fix(mix): rating filter across mixes and Lucky Mix queue fill (#714)

* fix(mix): apply rating filter across mixes and fix Lucky Mix queue fill

Invalidate entity rating cache on setRating and stop negative-caching
unrated artists/albums so filters see fresh stars. Honor UI rating
overrides, wire Instant Mix and CLI paths, fix Random Mix filter order,
and align Lucky Mix progress with the real player queue length.

* docs(changelog): document mix rating filter and Lucky Mix queue fix
