fix: return optional total balance in list apps response for subwallets (#2057)

* fix: return optional total balance in list apps response for subwallets * chore: add error handling to subwallet balance query * chore: add METADATA_APPSTORE_APP_ID_KEY constant * chore: add MAX_FREE_SUBWALLETS constant * chore: use subwallet query and total count for limit check
