fix: unify wheel Stars payment across desktop and mobile

- Use Telegram Stars invoice on all platforms instead of balance
  payment on desktop
- Show star cost in toggle and subtitle everywhere
- Show popup/toast when Stars are not enabled and user tries to spin
- Remove platform-specific payment type auto-select logic
- Add starsNotAvailable translation key (ru, en, zh, fa)
