c82e1d5a04 fix: 修复3D地球坐标映射多个严重bug 
## Bug修复详情

### 1. 致命错误：球面距离计算 (calculateDistance)
- 问题：使用勾股定理计算经纬度距离，在球体表面完全错误
- 修复：改用Haversine公式计算球面大圆距离
- 影响：赤道1度=111km，极地1度=19km，原计算误差巨大

### 2. 经度范围规范化 (vector3ToLatLon)
- 问题：Math.atan2返回[-180°,180°]，转换后可能超出标准范围
- 修复：添加while循环规范化到[-180, 180]区间
- 影响：避免本初子午线附近返回360°的异常值

### 3. 屏幕坐标转换支持非全屏 (screenToEarthCoords)
- 问题：假设Canvas永远全屏，非全屏时点击偏移严重
- 修复：新增domElement参数，使用getBoundingClientRect()计算相对坐标
- 影响：嵌入式3D地球组件也能精准拾取

### 4. 地球旋转时经纬度映射错误
- 问题：Raycaster返回世界坐标，未考虑地球自转
- 修复：使用earth.worldToLocal()转换到本地坐标空间
- 影响：地球旋转时经纬度显示正确跟随

## 新增功能

- CelesTrak卫星数据采集器
- Space-Track卫星数据采集器
- 卫星可视化模块（500颗，实时SGP4轨道计算）
- 海底光缆悬停显示info-card
- 统一info-card组件
- 工具栏按钮（Stellarium风格）
- 缩放控制（百分比显示）
- Docker volume映射（代码热更新）

## 文件变更

- utils.js: 坐标转换核心逻辑修复
- satellites.js: 新增卫星可视化
- cables.js: 悬停交互支持
- main.js: 悬停/锁定逻辑
- controls.js: 工具栏UI
- info-card.js: 统一卡片组件
- docker-compose.yml: volume映射
- restart.sh: 简化重启脚本
