feat: 删除部门模块 + 任务系统重构 + 布局修复

- 删除部门(Home)侧边栏入口、面板及相关代码
- 删除 home.js，chartOptions 等图表工具迁移到 utils.js
- 清理 render()、togglePhase、filterPhaseTasks 等死代码
- 任务列表改为平铺(取消阶段分组)，支持拖拽排序
- 任务表单加开始时间字段，重组字段布局为三列
- 任务展开面板改为竖排：时间、任务进展、卡点与备注
- 视图按钮和新增任务按钮移入任务卡片顶部
- 修复 index.html div 嵌套不平衡导致布局塌陷
- 修复 savedTab 校验和 switchTenant 侧边栏 active 同步
- 总览工作台只显示预算/发生总览入口
- 性能面板 id 去重
