Note

Adds loading/success toasts and new i18n keys for Predict orders, delays cash-out success, updates price formatting, and simplifies navigation by letting dispatch errors surface; tests updated.

• Predict Order Hook (usePredictPlaceOrder):
  • Adds loading toasts for BUY/SELL; shows success "prediction placed" or delayed "cashed out" toasts (2s) with new i18n keys under predict.order.
  • Uses strings('predict.order.*') and formatPrice(..., { maximumDecimals: 2 }); failure toast uses order_failed key.
• Views:
  • PredictBuyPreview: call placeOrder then immediately dispatch(StackActions.pop()); remove try/catch; onPlaceBet no longer async.
  • PredictSellPreview: same dispatch-after-placeOrder change; remove Alert usage; switch price formatting to { maximumDecimals: 2 }.
• i18n (locales/languages/en.json):
  • Adds predict.order namespace: placing_prediction, prediction_placed, cashing_out, cashing_out_subtitle, cashed_out, cashed_out_subtitle, order_failed.
• Tests:
  • Update to expect loading + success/failure toast sequences and delayed cash-out success.
  • Adjust navigation tests to expect thrown dispatch errors while still calling placeOrder.
  • Update formatting expectations to maximumDecimals: 2.
