style(ui): 统一底部操作栏按钮间距，取消所有gap样式

- 移除各底部操作栏（footer/__actions/page-actions）内所有gap属性
- 按钮间距统一采用 Element Plus 全局默认的相邻按钮12px margin-left规则
- 修改 .el-dialog__footer 内.el-button间距由8px调整为12px，保持全站一致
- 确认 Avue 表单底部按钮无自带间距，去gap后间距由 Element Plus 提供
- 涉及模块覆盖 vehicle、payment、business、settlement，移除了相关组件样式中gap属性
- MEMORY.md规范更新，补充底栏按钮间距统一为无gap纯文字规则

   - `#menu-form` 的运输计划创建模式次要按钮 `关闭` → `取消`。
   - 新增样式 `:global(.business-crud-form-page-dialog .avue-form__menu .el-icon){display:none}`：Avue 的 `avue-form` 提交/清空按钮内置图标（`submitIcon:'el-icon-check'`、`emptyIcon:'el-icon-delete'`），且 Avue 源码用 `||` 兜底无法通过 option 去除，故用 CSS 在独立表单页容器内统一隐藏图标，仅保留文字，不影响其它弹窗。
 - 规范固化：MEMORY.md「弹窗 / 独立表单页底栏按钮统一规则」补充「独立表单页 Avue 表单 footer 去图标（统一纯文字）」说明。

+## 底部操作栏按钮间距统一去 gap
+- 起因：用户指出这些底部按钮间距不一致，要求统一，并把用了 `gap` 的全部去掉。
+- 方案：所有底部操作栏（footer / `__actions` / `page-actions`）**移除 `gap`**，间距统一回落到 Element Plus 全局默认的相邻按钮 `.el-button+.el-button{margin-left:12px}`（恒为 12px），不再散落 `gap:8/12/16px`。
+- 全局对齐：`.el-dialog__footer .el-button + .el-button` 由 `margin-left:8px` 改为 `12px`（`src/styles/element-ui.scss`），使弹窗 footer 也与之一致。
+- 已去 gap 的 footer 容器：`vehicle/customer-archive.vue`(`.archive-form__footer`)、`business/components/master-order-editor.vue`(`footer`)、`business/components/master-order-dispatch.vue`(`.segment-actions`/`.pending-actions`)、`business/project-apply.vue`(`.project-apply-dialog__footer`)、`business/components/business-crud-page.vue`(`.business-crud-form-page-dialog .avue-form__menu`)、payment 6 个表单页(`*__actions`)、`settlement/components/pre-settlement-editor.vue`(`&__page-actions`)、`settlement/components/formal-settlement-editor.vue`(`.formal-editor__page-actions`)、`settlement/receivable-payable-detail.vue`(`.settlement-detail-page__actions`)。
+- 风控：确认 Avue 的 `.avue-form__menu`/`.avue-dialog__footer` 自身不带按钮间距，去掉 gap 后由 EP 默认 12px margin 接管（不会贴死）。
+- 范围说明：本次聚焦近几轮在统一的模块（vehicle/payment/business/settlement）。若要把 loading-manage、contract-manage、transit 等其它模块的底部栏也纳入，需再处理。

 ### 弹窗 / 独立表单页底栏按钮统一规则
 - **排序**：从左到右按次→主排（次要居左、主操作居右），主操作永远放最后。

-- **容器布局**：`display:flex; justify-content:flex-end; gap:12px;`。弹窗关闭按钮继承 Element Plus 自带 `.el-dialog__footer` 全局规则（见上条），独立页用 `.archive-form__footer` 配 `.archive-page-form & { position:fixed; right:0; left:230px; bottom:0; z-index:10; margin:0; padding:12px 24px; border-top:1px solid #eff1f7; background:#fff; box-shadow:0 -2px 8px rgba(0,0,0,.06); }`。
