feat: 用 react-map-gl + MapLibre 替换 react-simple-maps 实现 2D 地图

- 替换 react-simple-maps/d3-geo/topojson-client 为 react-map-gl + maplibre-gl
- 使用 CARTO dark-matter 免费暗色瓦片，自带国家/城市名标注
- 基于 locale 动态切换地图标注语言（name:zh / name_en）
- MapLibre 原生 heatmap + circle 双层渲染替代 SVG 热力图
- 提取 MapPopup 组件，配合 react-map-gl Popup 实现点击弹窗
- continent page 改为 dynamic import (ssr: false)
- dev 模式去掉 Turbopack 以兼容 maplibre-gl
- 删除 heatmap-layer.tsx 和 react-simple-maps 类型声明
