feat(manager/plans + biz-project): 审核 dialog 项目编号改远程 el-select

后端 (BizProjectController):
- 新增 GET /business/project/projectNoOptions
- 返回 [{projectNo, projectName}], 仅 project_no 非空, 按 projectNo 倒序
- 不加 @PreAuthorize (manager 是业务角色, 与 specialPlan/options 一致)

前端 (manager/Plans.vue):
- 模板: 项目编号 el-input → el-select (filterable, 显示 projectNo / projectName)
- script: 加 projectNoOptions ref + loadProjectNoOptions() 函数
- onAudit: 每次打开 dialog 调 loadProjectNoOptions 拿最新 options
