fix(小程序): 修正 v-for :key 表达式告警，恢复列表 wx:key

非 h5 平台的 :key 只接受简单属性名，模板字面量与运算表达式会被编译器
整条丢弃（uni-template-compiler 的 getForKey：Identifier 走 *this 或原名，
MemberExpression 取属性名，其余一律 warning + 返回空串）。

所以这批告警不只是文案问题：产物里对应的 <block wx:for> 后面确实没有
wx:key，列表项因此失去复用标识，增删时会整段重建节点。本次按编译器
接受的写法逐一改正，共 13 个文件。

改法：
- 纯 URL 字符串数组（打卡/门头/小票/凭证/巡店照片）直接用元素自身
  :key="img"，编译为 wx:key="*this"
- 对象数组用其已有唯一字段：连锁/门店 item.id、抄送用户 user.id、
  审计销量行 detail.key、编辑销量项 detail._key
- 本身无唯一字段的巡店列表补 _key：task/detail 沿用 visit.vue 已验证的
  _rowKey（自增 seed，增删稳定），records 与 AuditVisitReportItem 用序号

sales.vue 另有一处隐蔽问题：row 是 {item, index} 包装对象，
:key="row.item._key || row.index" 即便写成简单形式也会生成 wx:key="_key"，
在 row 上取不到值。改为在 visibleSalesItems 里把 key 提到包装对象顶层，
_key 缺失时用序号兜底。create.vue 的销量摘要同样补 __key 兜底，避免重复 key。

注：task/detail 的 storeList 提交走 sanitizeStoreList() 显式白名单，
_rowKey 不会外泄到后端。

验证：HBuilderX cli 重新编译 —— 编译成功，非 h5 平台 :key 告警 0 条
（修改前满屏 40+ 条），产物中 wx:for 与 wx:key 数量逐文件相等。
