fix(dl): preserve per-language video selection in quality step

Browse Source 
The video quality Cartesian product (resolution × range × codec) only picked the first matching track, collapsing multi-language selections back to a single language. Add language as a product dimension when -l best/all or -vl with multiple languages is used.
