feat(cmpt): 添加微信分享图功能

## 功能描述
为赛事详情添加微信分享图字段，支持在后台管理上传和维护微信分享图片。

## 变更内容
### 后端修改
- Cmpt.java: 新增 wechatShareImage 字段，带有 API 文档注解
- CmptMapper.xml: 更新所有相关查询，包含 wechat_share_image 字段
  - queryCmptBycmptId: 查询单个赛事
  - queryCmpt: 查询赛事列表
  - queryCommitteeCmpt: 查询组委会赛事
  - queryMyCmpt/queryMyCmptList: 查询我的赛事
  - updateCmpt: 更新赛事信息
  - save: 保存新赛事

### 前端修改
- index.jsp: 在赛事 LOGO 下方新增微信分享图上传区块
  - 保持与 LOGO 上传相同的 UI 风格
  - 提示建议尺寸比例 5:4（如：1000*800px）
- index.js: 更新保存逻辑和图片上传处理
  - saveCmpt 函数新增 wechatShareImage 参数
  - changeLogoImg 函数支持微信分享图上传

### 数据库变更
- database_migration.sql: 提供 ALTER TABLE 脚本
  - 新增 wechat_share_image 字段（VARCHAR(500)）
  - 字段位置在 logo 字段之后

## API 影响
- 小程序端 API 自动返回 wechatShareImage 字段（通过 Cmpt 实体）
- 后台管理 API (/gk/cmpt/saveCmpt) 支持保存微信分享图

## 测试建议
1. 在后台管理上传微信分享图
2. 验证图片正确保存和显示
3. 确认小程序端能正确获取微信分享图 URL
