换币客户改在交易终端成交：按比例部分成交、买币随机出价、弹出钱包

- 对话只剩"到终端上谈 / 这单我不做"：交易终端打开柜台交易页（标签"柜台"，只在有客户时出现），客户在柜台前等着
- 柜台交易页：客户来意、数量、市值、出价/要价、单价、地址（卖币可"查地址"进浏览器），25/50/75/100% 或手输数量部分成交（Otc.Part），成交 / 放弃
- 买币客户随机出价（OtcBidMin −5% … OtcBidMax +30%），去掉三档报价与成交概率（OtcPremium、OtcAccept）；成交后弹出 PLEDGER，账单 Prefill 填好客户地址
- 卖币：成交后付现金、币进已连接的钱包；客户说最后一句离开（DialogUIManager.StartDialogue）
- 客户被打发或离开时交易作废；不再有"当晚未付作废"
- 增量翻译：只是和已删旧键同文的新键照常翻译
- 实测：买币客户 25% 部分成交（先在 Web3 换出 CRA），PLEDGER 预填地址签名，到账 +668，客户离开；涡轮增压器作用于矿架立刻挖一轮
