改善提案
删除流程功能：
为已发起且仍在处理中的改善提案增加“删除流程”操作。删除后终止当前 Flowable 实例、清理本轮流程数据，并将提案回退为草稿，允许重新编辑和发起。
Implementation Changes
后端新增 POST /improvementproposal/improvementProposal/withdrawProcess?id=...，复用现有 improvementproposal:improvement_proposal:delete 权限。
在 ImprovementProposalService 新增事务方法：锁定主表后，仅允许 bpm_status='2' 且存在运行中流程实例的提案撤回；流程已完成、已作废、草稿或实例不存在时拒绝操作。
参考党委会的流程清理方式，终止 Flowable 运行实例并删除该实例的历史、审批意见、抄送、流程中间数据和流程日志；不改动全局流程引擎代码。
删除本轮 improvement_dept_score、improvement_institute_vote 数据，避免重新发起后复用旧评分、投票结果。
将流程衍生字段清空：流程实例、初审/评分/负责人奖项、评分汇总、所级投票人数与结果、最终奖项、人工确认、归档人及归档时间；保留提案基本信息、编号和业务附件。
将主表 bpm_status 重置为 1，使现有编辑、删除和发起流程逻辑自动恢复可用。
前端台账操作菜单在处理中记录显示“删除流程”，增加明确提示“删除后将回退为草稿，当前评分、投票和审批数据将被清空”；成功后刷新列表。
不增加批量删除流程功能，现有批量删除仍只处理草稿。
