feat(entity): 为工单实体添加附件字段的JSON序列化处理

Browse Source 
- 在AppTicket和AppTicketReply实体中添加JsonArrayToStringDeserializer和JsonStringToArraySerializer注解
- 实现附件字段在数据库存储时从数组转换为JSON字符串
- 实现附件字段向前端响应时从JSON字符串转换为数组格式
- 添加JsonArrayToStringDeserializer类处理数组到字符串的反序列化
- 添加JsonStringToArraySerializer类处理字符串到数组的序列化
- 移除CMS网站映射器中的软删除条件过滤
