style(forms): 全站表单项间距统一调整为14px

- 统一调整settlement、business、payment模块以及全局样式中.el-form-item的margin-bottom从16/18/20px改为14px
- 保留搜索栏相关的.el-form-item间距为8px和特殊分组risk-disposal的28px
- 修正多个页面和组件的局部样式覆盖问题，确保填写区表单项间距一致
- 更新element-ui.scss中.dialog-form--carded对应的margin-bottom为14px
- 维护部分表单组件原本使用的重要样式不变，保证视觉统一且不影响特殊布局

+## 全站表单项间距统一 14px
+
+**诉求**: `settlement/pre-settlement/form?mode=add` 中 `.el-form-item` 间距偏大，要求统一为 14px 且全站一致（用户指"表单项间距"）。
+
+**排查**: 全站 `.el-form-item` 的 `margin-bottom` 取值不一致——表单填写区有 16px / 18px / 20px，
+搜索栏统一 8px（保留），个别特殊分组 28px（risk-disposal，保留）。全局 `.el-form-item--default`
+已是 14px，但各页面 scoped `:deep(.xxx .el-form-item)` 覆盖成了 16/18/20px。
+
+**改动（表单填写区统一 14px，16/18/20 → 14）**:

+
+**保留未动**: 所有 `__search` 搜索栏的 8px、risk-disposal 的 28px 特殊分组、transportCapacity
+vehicle/driver/ship 与 customer-archive 等本就是 14px（含 !important）。
