feat: 将数据库模型和迁移集中到 EFCore 项目

Browse Source 
- 将 AppDataContext、实体模型、Migrations 从 Avalonia-Services 移动到 Avalonia-EFCore
- 更新 API、PC、Services 中的数据库上下文和实体引用命名空间
- 在实体上显式绑定表名、字段名和数据库注释
- 更新 InitialCreate、Designer、Snapshot，使用新的表名、字段名和注释
- 新增 AppDataContextFactory，支持 dotnet ef 设计时创建 DbContext
- 新增本地 dotnet-ef 工具清单
- 新增一键生成迁移脚本 add-migration.ps1 / .cmd / .bat
- 启动时自动检测并执行未应用迁移
- 从 appsettings.json 读取数据库配置
