项目 8 智慧校园管理平台：5 个任务的示例、自绘素材、WisdomCampus 数据库

- 示例 p8-t1…t5（代码逐个累加）：主界面、校园环境界面、环境采集与分析（路灯手动 / 自动控制、
  LED 推送、自动推送火情、7 天温度图表）、校园安防（入侵提示、摄像机方向、拍照入库）、历史图片
  （按日期查询、左右切换），各有评分规则
- 按书补全参考工程里空着的"推送LED信息""自动控制"，给"自动推送火情"绑定 CheckedChanged
  （书上第 23 步写成了 ch_autoLamp）；任务 5 每次查询前清空 Keys
- 素材：项目 8 的 20 多张图片全部自绘，名字和尺寸与教材一致（project8.py 生成 SVG，
  build-gallery.sh 渲染成 PNG；源文件移到 svg/）
- 数据库 WisdomCampus 按教材的表结构建（EnvironmentData、SecurityData、Users），预置 7 天环境数据
- 测试：参考答案全部通过；没绑定"自动推送火情"、开灯换错背景图片时报出对应原因
- 文档：教材 8 个项目全部有示例，共 23 个
