feat: 资源申请模块重构——清理816行死代码+提取共享helpers+修复类型标签bug

- 删除 CabinetView.tsx(422行) + ResourceModelManager.tsx(394行) 死代码
- 提取 approval/helpers.tsx 共享辅助函数(parseSteps/parseFields/renderFormData/
  getProgressInfo/renderStepProgress/APPROVAL_TYPE_OPTIONS/getInstanceType)
- 修复审批类型标签bug：instance无type字段，需从template.type取
  (getApprovalTypeLabel/Color/Icon 全部改用 getInstanceType(instance))
- ApprovalFlow.tsx 771→666行(低于700限制)
- ApprovalProcessTab.tsx 移除重复helpers+过期类型字典(deploy/server/permission→server_apply/app_deploy)
