The update operation for Model previously overwrote `created_time` with zero
because GORM included every struct field in the UPDATE statement.
This commit adjusts `Model.Update()` to:
* Call `Omit("created_time")` so the creation timestamp is never modified.
* Refresh `UpdatedTime` with `common.GetTimestamp()` before persisting.
* Delegate the remainder of the struct to GORM, eliminating the need to
maintain an explicit allow-list whenever new fields are introduced.
No API contract is changed; existing CRUD endpoints continue to work
normally while data integrity for historical records is now guaranteed.

// Model 用于存储模型的元数据，例如描述、标签等

|
// ModelName 字段具有唯一性约束，确保每个模型只会出现一次
|
|
// Tags 字段使用逗号分隔的字符串保存标签集合，后期可根据需要扩展为 JSON 类型
|
|
// Status: 1 表示启用，0 表示禁用，保留以便后续功能扩展
|
|
// CreatedTime 和 UpdatedTime 使用 Unix 时间戳（秒）保存方便跨数据库移植
|
|
// DeletedAt 采用 GORM 的软删除特性，便于后续数据恢复
|

//
|
|
// 该表设计遵循第三范式（3NF）：
|
|
// 1. 每一列都与主键（Id 或 ModelName）直接相关
|
|
// 2. 不存在部分依赖（ModelName 是唯一键）
|
|
// 3. 不存在传递依赖（描述、标签等都依赖于 ModelName，而非依赖于其他非主键列）
|
|
// 这样既保证了数据一致性，也方便后期扩展
