feat: 统一角色枚举 (meetingExecutor/supervisor) + 子账号数据隔离 + Login 读取后端 role_type

后端:
- SysUser 加 roleType 字段 (entity + mapper selectUserVo + service 接口/实现)
- SysUserMapper 新增 selectUserIdsByParent (按 parent_user_id 取子账号列表)
- BizPersonController.list 自动注入 MAIN 业务用户可见性: 仅查 user_id IN (子账号列表)
- BizPersonMapper 加 params.subUserIds foreach 过滤
- BizPerson/BizPersonServiceImpl 配合 getParams().put

前端:
- Login.vue 改用后端 sys_user.roleType 替代 username 前缀 autoRole, 修复 exe01 错入 leader 菜单
- utils/roleMap.js 新增: meetingExecutor->会议执行, supervisor->监察员
- executor/People.vue / sponsor/NewPerson.vue / sponsor/Projects.vue / sponsor/SponsorProjects.vue /
  manager/ManagerProjectDetail.vue / manager/{Executor,Sponsor}PersonNew.vue /
  admin/{Executor,Sponsor}PersonNew.vue 全部改为 enum key

SQL:
- migration_unify_role_type_2026_08_16.sql 清洗 biz_person.role 从中文到 enum key
