…L, ja→JPY) #304 removed the language→currency mapping and stopped sending stripe_currency, but the backend requires it, which broke checkout; #306 hot-fixed by hard-defaulting USD. Result: pt/ja users always get a USD checkout. Stripe local payment methods are currency-gated (Pix requires BRL, Konbini requires JPY), so those users can never see local payment methods even once enabled in the Stripe dashboard. Restore the language-based default as a fallback only: an explicit ?currency= search param still wins, all other languages keep USD. Backend BRL/JPY price contracts already exist (expectedStripeTopUpAmountMinor). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

问题 / 背景
巴西/日本用户的 Stripe 收银台永远是 USD——而 Stripe 的本地支付方式是按结算货币门控的（Pix 只在 BRL 下出现、Konbini 只在 JPY 下出现）。这意味着即使在 Stripe Dashboard 开通 Pix，巴西用户也永远看不到它。这是 #292（收银台弃单救回）的前置缺口。
