style(process-config): 优化流程配置页样式及结构一致性

- process-config.vue 基本信息区改用 section-card 和 el-form 组件，统一右侧固定宽 label 栅格布局
- 现行过程节点和节点设置区使用 section-card 包裹，替换原有灰色标题，增加白卡样式和卡片间距
- 删除不再使用的自定义样式 __section/__field/__field-label/__field-label--required，保留与节点表格相关样式
- 保证三个 section-card 正确闭合，编译通过，无业务逻辑变更
- master-order-detail.vue 主界面改用 section-card 代替 div 容器，提升风格统一性
- 注释部分 Element UI 弹窗表单项 margin-bottom 样式，减少样式冗余
- loading-manage.vue loading-detail 取消 flex gap，防止潜在样式冲突
- shipping-template.js 表单项 grid 栅格 span 值调整优化表单布局，使各项宽度分配更合理
