feat: 整体废弃 leader 业务角色

leader 角色 (项目负责人) 业务上已不再使用, 整体下线。仅保留 sys_dept.leader 字段 (部门负责人, RuoYi 标准字段, 与角色无关)。

前端清理 (15 文件):
- 路由: 删除 /leader 块 + 4 子路由 (router L56-61)
- 菜单: 删除 AdminLayout 中 leader 菜单 (5 行)
- 视图: 删除整个 views/leader/ 目录 (Home/Projects/Meetings/Account.vue 共 ~32KB)
- Login.vue: 删默认 role='leader', 删 leader 角色选项, 删 autoRole 的 leader 分支, 删 roleHome 的 leader 项
- PortalShell.vue + 5 个 portal/* (Home/Publicity/ArticleView/PublicityDetail/SpecialPlanDetail): admin fallback '/leader/home' → '/admin/workbench', 删 leader 项, 同步更新 admin 入口 (/leader/home → /admin/workbench)
- 5 处 ROLE_LABEL 字典删 leader: '项目负责人' (AdminLayout/Account/Roles/Users/Workbench)
- Roles.vue 注释同步

后端清理 (7 文件):
- BizDashboardController: 删除 /leader dashboard 端点 (整个方法)
- BizPersonController: BUSINESS_MAIN_ROLES 删 leader
- BizExecutorController/BizProjectPlanController/ISysUserService/SysUserExtendVo/SysUser: 注释同步删 leader

测试:
- test_20rounds.py: 删 leader 路由断言 + view_map + role_home + role_view 共 5 处

未做 / 后续:
- DB: sys_user.role_type='leader' 现存账号是测试账号, 用户确认可忽略, 后续手动清理
- 文档: proto/html/leader.html 等原型文件保留 (历史)
- _self/*.md 笔记提及 leader 不动 (笔记)
