refactor(process-config): 重构过程配置弹窗为手写 el-dialog

- 将 process-config 弹窗由 Avue 内置弹窗改为手写 el-dialog 对齐 customer-archive 风格
- 移除 avue-crud 原有的弹窗相关生命周期和插槽方法
- 新增 openProcessConfig、submitProcessConfig、resetProcess 等方法管理弹窗状态和数据提交
- 更新模板结构，新增具备基本信息、过程节点、节点设置的表单布局和底部操作按钮
- 关闭原 avue-crud 弹窗的内置按钮，改由手写对话框控制操作
- 优化样式，增加弹窗内部滚动，保持 footer 固定
- 微调业务组件样式，调整边框和表单布局宽度以适配新弹窗设计
