feat(项目管理): 招标字段/负责人/导出/下拉/登录短信 完整链路

后端 (ruoyi-business)
- BizProject: +is_bid_project, +execOrgNames(GROUP_CONCAT派生), +leadUserName
- BizProjectMapper.xml: 上述字段全部贯通 selectFields/insert/update, 列表加 exec_org_names 子查询 + lead_user_name JOIN
- BizSysUserQueryMapper (新): 干净查 sys_user by role_type, 避开 @DataScope 切面污染, 用于项目负责人下拉
- BizOrgMapper.selectExecutorOrgOptions (新): JOIN sys_user (parent_user_id IS NULL) 限定 MAIN 账号, 排除同公司普通员工子账号
- BizOrgController: +/business/org/executorOptions 端点
- BizExecutionIntentController: +exportSignupExperts 端点 (POST /business/executionIntent/export)
- BizSignupExpertExportVo (新): 中文列头 Excel 导出 VO (专家姓名/科室/医院/职称/报名时间/手机号)
- BizProjectAssign / SponsorAssign 重命名 + Service 实现调整
- 删除 sql/ 下所有迁移脚本 (按用户要求不再保存 SQL 文件)

前端 (ry-vue3)
- api/system.js: +listExecutorOrgs 走新接口, listExecutor/listSupporters/listManagers 保持 listByRole 兼容
- views/manager/Projects.vue: 执行方下拉改 label=u.orgName / value=u.userId, 数据源走 listExecutorOrgs
  +execOrgNames 列展示 +导出报名专家 dropdown 项 +is_bid_project 表单字段
- views/manager/ProjectsNew.vue + ManagerProjectDetail.vue: +is_bid_project 表单/展示
- views/auth/Login.vue: +手机号验证码登录 tab (复用 SysSmsService, dev 模式 10 开头手机号固定码 1234)
- 路由/布局/角色视角多页面整理 (SponsorOrgs/People/SponsorPersonNew 等)
