feat(platform): 增强 Infrastructure 层可扩展性，添加 NuGet 发布脚本与 CI/CD

## 主要变更

### Infrastructure 层重构
- `PlatformDbContext`: 构造函数改为接受泛型 `DbContextOptions`，支持派生上下文
- `TenantStore<TContext>`: 泛型化实现，支持不同的数据库上下文
- `Extensions`: 新增 `AddPlatformCore<TContext>` 扩展方法，简化服务注册

### 依赖调整
- 移除 Npgsql.EntityFrameworkCore.PostgreSQL 直接依赖，由使用方自行决定数据库提供程序

### CI/CD 集成
- 新增 `.gitea/workflows/publish-nuget.yml` Gitea Actions 工作流
- 新增 `push-platform-nuget.sh` 脚本，支持：
  - 从 git tag 自动获取版本号
  - HTTP/HTTPS 双模式支持
  - 独立 NuGet 配置文件
  - CI/CD 友好的环境变量配置

### 其他
- `NuGet.Config`: 新增 NuGet 配置文件
- `Fengling.Platform.Domain`: 添加 Items 文件夹占位
