feat(android): chunk Home Recently-Added into 25-album carousels (audit v3 §4.6)

A large library rendered all recently-added albums in one horizontal
LazyRow that scrolled forever. Now the list is chunked into stacked
carousels of 25 (RECENTLY_ADDED_CHUNK); the first carries the
"Recently added" title and the rest are untitled continuation rows,
matching Flutter's shared-ScrollController layout.
