feat: 完成配置管理增强功能

## 修复问题

### 1. 企业加载不出来
**问题**：`Unknown column 'company_id' in 'table list'`
**原因**：`t_company` 表中字段名是 `id` 而不是 `company_id`
**修复**：修改 `/api/entities` API 中的SQL查询，使用正确的字段名

### 2. 用户加载不出来
**问题**：`Unknown column 'name' in 'field list'`
**原因**：`t_user` 表中字段名是 `user_name` 而不是 `name`
**修复**：修改SQL查询，使用正确的字段名 `user_name`

## 新增功能

### 3. 拆分方式增加"按场站"
- 在拆分方式下拉框中添加"按场站"选项
- 支持从 `t_station` 表加载场站列表
- 场站显示名称格式：`station_id - name`

### 4. 企业/用户/场站多选功能
- 将选择框改为多选（`multiple` 属性）
- 保存时将多个值用逗号分隔存储
- 编辑时自动解析逗号分隔的值并选中对应选项
- 日报生成时支持多选值查询（使用 IN 语句）

### 5. 配置复制功能
- 在配置列表中添加"复制"按钮
- 复制配置时自动添加"_副本"后缀
- 后端API：`POST /api/config/<id>/copy`

### 6. 后端查询优化
- 修改 `report_generator.py` 中的查询逻辑
- 支持多选值查询（逗号分隔的值使用 IN 语句）

## 重启应用测试

```bash
# Ctrl+C 停止
python app.py
```

然后刷新页面，测试：
1. ✅ 企业/用户/场站列表是否正常加载
2. ✅ 多选功能是否正常工作
3. ✅ 配置复制功能是否正常
4. ✅ 生成日报时多选值是否正确查询
