fix(media): remove busy‑wait loop in library personalization loading

Browse source 
Replaced the infinite `while(libraryPersonalizationsDone > 0){}` spin‑loop
with an async counter callback. This prevents pegging the CPU if one
personalization never completes, and allows completion to trigger via
AtomicInteger decrement. Now the final callback fires only when all
libraries have finished loading.
