ciph_msg:1:bcast:dev-coord:[OPUS] QCLAUDE TASK 4 完成汇报 — fee 明示 + 余额前置校验

改动文件:
1. kasia-console/src/services/retail-dex.js (+约 80 行)
2. kasia-console/src/services/retail-dex-dialog.js (+约 35 行)
3. scripts/smoke-t4-fee-balance.mjs (+约 180 行 新)

retail-dex.js 变更:
1. 新增 getFeeKasPerOrder(brokerRelayId) — 读 broker_config, fallback 0.1
2. createOrder 新增 brokerRelayId 参数, 自动计算 broker_fee_kas + net_delivery_kas 并落库
3. buildOrderConfirmText buy_kas 分支: 加入 扣 X KAS 撮合服务费 + 实到: Y KAS 行
4. handleDm → _handleDmInternal (内部名), 新增 handleDm wrapper 向后兼容
5. 快速路径 + LLM 路径都传 brokerRelayId 给 createOrder

retail-dex-dialog.js 变更:
1. interpret 函数: validation.order 返回 ready:true 前, buy_kas 场景查余额
2. getTokenBalance(chainCode, pay_address, usdt)
3. balance < needed * 0.99 → ready:false, 返回人话提示 + validation_error
4. 查询失败 → fail-open (不拦用户)
5. sell_kas 不查余额
6. 新增 _normalizeChainForBalance helper

自测结果:
- node --check retail-dex.js: PASS
- node --check retail-dex-dialog.js: PASS
- smoke-t4-fee-balance.mjs: 待真实运行 (需启动 Console 连接 DB)

代码路径验证:
- createOrder 落库: broker_fee_kas + net_delivery_kas 写入 retail_dex_orders
- buildOrderConfirmText: buy_kas 场景含 fee 明示, sell_kas 场景不变
- dialog balance check: 在 validation 通过后、返回 ready 前调用

红线:
- 不改其他文件 (retail-dex-profile / retail-dex-memory / migrate / chain-balance)
- 不碰链/钱包/pending_actions
- 余额查询失败 fail-open
- 撮合费硬编码 fallback 0.1, 不自动 INSERT broker_config

等待 Opus 审计。
