feat(wish-tree): 许愿树页面微调七项

1. 背景图 aspectFill 撑满全屏，挂载点坐标按裁剪比例重算，便签不再落在图外
2. 写下心愿按钮单行不换行，缩小尺寸
3. 移除页面内许愿树标题/数量/最近心愿，点击便签弹出便签式详情卡
4. 默认请求100条：最新50条挂树，其余以弹幕形式缓缓飘过
5. MAKE A WISH 下方增加顶级位置轮播（购买后24小时内展示），点击弹出金色便签详情，与普通便签区分
6. 多棵树分屏轮播（swiper），背景图从服务器获取，带指示点
7. 后端：WishTree新增image字段，Wish新增isTop运行时标记，图片用go:embed内嵌随二进制部署，/images路由提供访问
