feat(store): 更新生命优惠券实体字段填充策略并优化服务逻辑

- 为 LifeCoupon 和 LifeDiscountCoupon 实体中的多个字段添加 TableField 注解，
  设置 fill 属性为 FieldFill.UPDATE，以支持自动填充更新操作
- 在 LifeCouponPlatformController 中优化获取优惠券详情时的字段处理逻辑，
  对 singleQty、singleCanUse 和 purchaseLimitCode 字段做空值或默认值转换
- 在 LifeCouponPlatformServiceImpl 中新增对 singleQty 的初始化校验逻辑，
  若该字段为空则设置为 0
- 在 LifeDiscountCouponPlatformServiceImpl 中增加对 minimumSpendingAmount
  是否为零的判断，并在为零时设为 null，避免前端显示无效数值
- 所有修改均围绕提升数据一致性与接口返回规范性展开，增强系统健壮性和可维护性
