fix(android): add Hilt @Provides for CachedHomeIndexDao

HomeRepository's CachedHomeIndexDao constructor injection failed with
"cannot be provided without an @Provides-annotated method" — the DAO
existed on AppDatabase but the per-DAO bridge in DatabaseModule was
never added (no consumer until HomeRepository landed).
