Merge PR #478: stagger-анимация скрывала контент, пришедший из API после mount

framer-motion stagger раздаёт детям команду показаться один раз при монтировании
родителя; дети, смонтированные позже (когда resolve-ится react-query), оставались
в initial (opacity:0) — пустые страницы после F5/прямого захода.

- ConnectedAccounts, SavedCards: key={isLoading?...} перемонтирует контейнер
  после загрузки → stagger проигрывается со всеми детьми;
- Balance (2), Profile, Support: явные initial/animate на условных staggerItem —
  элемент самоанимируется при mount, вне оркестрации родителя;
- Wheel: исправлены несуществующие варианты hidden/show → initial/animate
  (stagger истории спинов молча не работал).

Валидация на смердженном дереве: tsc, biome lint/format, build — чисто.
Правки #477 и #478 в общих файлах (ConnectedAccounts/Profile) сосуществуют.
