fix: 使用 form_data 存储运行时审批人，不修改 approval_node 模板

主要修改：
1. submit() 方法不再修改 approval_node 表，节点仅作为流程模板
2. getList() 的 pending 查询从 form_data.approvers 获取审批人列表
3. approve() 方法从 form_data.approvers 检查用户是否有权限
4. 兼容两种数据格式：[1,2,3] 或 [{id:1},{id:2},{id:3}]

修复问题：
- 之前每次提交申请都会修改 approval_node 表的 approvers 字段
- 这导致流程模板被污染，不同的申请共享同一个节点配置
