v1.2.49：请假审批人「候选为空可不选」+ 新增抄送人（非必填，候选取自审批人列表）——① 审批人校验放宽（实测驱动）：ysdwl「大四学生请假」needApproval=1 但审批节点（政工队伍应用管理员）未配置人员，obtainApproveFlow 返回空列表，旧逻辑强制必选导致用户无法提交；现前端在候选为空时不显示必选星号、提示「该校未配置审批人，可不选」，校验仅在有候选时要求选择；后端 execute 校验同步改为「needApproval=1 且候选非空才必填」（服务端自行查候选，避免前端被绕过），候选为空时记录日志放行；② 抄送人功能：ccInfo 从硬编码空结构改为按用户选择构造（BuildLeaveCcInfo），按 userWid 去重、按 userId 是否纯数字分组 teachers/students（personType 0/1，官方结构含 name2Id/dept/sex/teacherName 字段）；前端抄送人区显示条件与 needApproval 解耦（候选同源 obtainApproveFlow，类型+时间齐全即加载），蓝色复选框多选、非必填，类型/时间变化后自动清理失效选择；③ 静默降级：候选加载失败不再弹错（避免每次切换类型红字打扰），需审批时提交由后端复核并给明确提示；④ 新增 TestBuildLeaveCcInfo 覆盖学生/教师分组、空列表、表单携带；go test ./...、go vet、vue-tsc、npm run build 全过
