refactor(gateway): adapt to Platform 1.0.12 entity changes

- Remove IInstanceStore DI registration (replaced by IClusterStore)
- Remove GwTenant and GwServiceInstance from ConsoleDbContext config
- Update GatewayService to use Match.Path instead of PathPattern
- Cast RouteStatus enum to int for Status field
- Add 04-SUMMARY.md documentation

+# Phase 4 总结：适配 Platform 1.0.12 Gateway 实体变更
+
+## 概述
+
+本次 Phase 4 成功完成了 Fengling Console 对 Platform 1.0.12 Gateway 实体变更的适配工作。
+
+## 主要变更
+
+### 1. Program.cs 依赖注入更新
+
+**变更内容：**
+- 移除了 `IInstanceStore` 和 `InstanceStore` 的注册
+- 保留了 `IClusterStore` 和 `ClusterStore` 的注册
+
+**变更原因：**
+Platform 1.0.12 移除了 `IInstanceStore` 接口，实例(Destination)现在是 `GwCluster` 的内嵌对象。
+
+### 2. ConsoleDbContext 实体配置清理
+
+**变更内容：**
+- 移除了 `GwTenant` 实体配置（原平台中已移除）
+- 移除了 `GwServiceInstance` 实体配置（已重构为 GwDestination）
+
+### 3. GatewayService 实体属性适配
+
+**变更内容：**
+
+| 旧属性 | 新属性 | 说明 |
+|--------|--------|------|
+| `GwTenantRoute.PathPattern` (string) | `GwTenantRoute.Match.Path` ( GwRouteMatch.Path ) | 路由匹配配置从简单字符串升级为复杂对象 |
+| `Status = RouteStatus.Active` (enum) | `Status = (int)RouteStatus.Active` (int) | Status 字段为 int 类型，需要显式转换枚举 |
+
+**具体代码变更：**
+
+```csharp
+// 旧代码
+new GwTenantRoute
+{
+    PathPattern = pathPattern,
+    Status = RouteStatus.Active,
+}
+
+// 新代码
+new GwTenantRoute
+{
+    Match = new GwRouteMatch { Path = pathPattern },
+    Status = (int)RouteStatus.Active,
+}
+```
+
+```csharp
+// 旧代码读取
+r.PathPattern
+r.Status
+
+// 新代码读取
+r.Match.Path
+r.Status (已是 int)
+```
+
+## 编译结果
+
+✅ 编译成功，0 个错误，3 个警告（警告为预存在的代码质量问题，与本次变更无关）
+
+## 验证
+
+- [x] `dotnet build` 通过
+- [x] 无新增编译错误
+
+## 相关文档
+
+- 实体变更详情：`.planning/docs/gateway-entity-changes-1.0.12.md`
+
+## 下一步
+
+可以考虑的改进：
+1. 修复 TenantService.cs 中的警告（roleManager 参数未使用）
+2. 完善 GatewayService 中的空值处理（Match 可能为 null）
