修复在 EF Core 10 中使用 JSON 值对象时出现的映射错误：
## 问题
在 EF Core 10 中，GwRouteMatch 类的嵌套集合属性（Headers 和 QueryParameters）
导致 "Unable to determine the relationship" 错误。
## 解决方案
1. 在 PlatformDbContext 中使用 modelBuilder.Ignore<> 忽略相关类型
2. 将 OwnsOne().ToJson() 配置改为使用值转换器（Value Converter）
将对象序列化为 JSON 字符串存储到 jsonb 列
3. 在 GwRouteMatch 类的 Headers 和 QueryParameters 属性上添加 [NotMapped] 特性
4. 添加 [JsonInclude] 特性确保序列化包含这些属性
## 技术细节
- 使用 HasColumnType("jsonb") 存储 JSON 数据
- 使用值转换器处理对象序列化/反序列化
- 保持与 PostgreSQL jsonb 类型的兼容性
## 文件变更
- 修改: Fengling.Platform.Domain/AggregatesModel/GatewayAggregate/GwRouteMatch.cs
- 修改: Fengling.Platform.Infrastructure/PlatformDbContext.cs
关联任务: IMPL-4 (EF Core 兼容性修复)
关联重构计划: WFS-gateway-refactor
