feat: 重做灵动岛编辑器与课表档案时间表编辑

灵动岛
- 重构自定义方案编辑器：组件库常驻、拖拽添加与排序、方案切换/新建/复制/删除、编辑模式预览与缩放，容器在编辑时展开全部子组件。
- 新增天气简报组件：主进程固定请求 Open-Meteo，只接受数值经纬度，失败退避并保留本次运行缓存；冒烟模式不访问外网。
- 倒计时支持目标名称与日期；课程表组件新增「今日时间点」，按时间点类型折叠/展开，课中不再常驻倒计时。
- preload 暴露 getIslandWeather 与时间点订阅，契约同步 desktop.d.ts。

课表档案
- 时间点默认课程：布局返回 defaultCourse，日课表没有条目时回退；新增 apply-default 覆盖所有引用课表；全校时间表不携带默认课程。
- 新增 ClassIsland 式时间表编辑器（列表/时间轴视图、拖动把柄、按类型添加、默认时长与缩放）与「课表信息」表单。
- 课表页默认进入单表编辑，底部保留列表/周/月视图；时间表支持新路由删除。
- 「课间」统一改称「课间休息」。

验证
- pnpm typecheck、pnpm lint 通过。
- verify:e2e 隔离验收 248/248 项通过（含默认课程回退、覆盖写入与时间表删除）。
- ui-smoke 覆盖单表编辑、课表信息与时间轴视图，并更新回归截图。
