feat: 提现优化 — 取消状态 + 收款方式 + TableName 修复 (HIF-42)

- P04: 修复 Withdrawal.TableName() 返回正确表名 withdrawals
- P03: 新增提现状态常量 (constant/withdrawal.go)，消除魔法数字 0/1/2/3；
       新增 CommissionTypeWithdrawCancel (338) 和 WithdrawalCancelForbidden 错误码
- P02: 迁移 02123 为 withdrawals 表添加 method/account/qr_code_url 列；
       扩展 Withdrawal GORM 模型和 API 类型（CommissionWithdrawRequest、WithdrawalLog）；
       申请提现时增加收款方式校验逻辑
- P01: 新增用户取消提现接口 POST /v1/public/user/withdrawal_cancel；
       仅可取消自己的待审核提现，退还佣金并写佣金日志
- P05: 管理端提现列表新增 method 过滤参数
