核心改造： 1. Wallet模块DTO层全部改为*Cent int64字段 2. Wallet.Entry结构从Amount float64改为AmountCent int64 3. Repository层applyEntry函数使用整数加减，无需浮点运算 4. Withdrawal模块DTO/Request全部改为*Cent字段 5. 所有wallet.AppendEntries调用点改为AmountCent 6. 提现手续费计算改为分单位 技术细节： - 删除了roundWalletMoney函数（不再需要） - toAccountDTO/toLedgerDTO使用*Cent字段 - 最小提现金额：10元=1000分 - 最大提现金额：5000元=500000分 - 编译验证通过 ✅ Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
