feat: 多项目页面模板系统（P6）

- ProjectProfile 新增 PageLayoutConfig（rightColumnWidth + hiddenSections）
- ProjectViewModel 暴露布局属性（RightColumnWidth/HasRightPanel/各区块 IsHidden）
- ProjectView.axaml 各区块绑定 IsVisible 到配置
- ProjectView.axaml.cs 动态调整 Grid 列宽（ApplyLayout）
- yangjie2.json 增加默认 layout 配置示范
- 新项目可通过 JSON 配置隐藏特定区块或调整右栏宽度
