feat(web): 海选按场景分组 + 删场景点位页签 + 演出真实底图 + 破缓存

- 海选审核左侧改两列：场景列(按新字段 ir.scene 手动归类聚合，含全部/未分类) + 该场景事件列
- 删独立「场景/点位」页签(pointview.js 保留未引用)
- 演出配置 Timeline 接真实场景俯视底图(setupShot 覆盖投影范围 + drawStage 叠图，复用 /api/pointsets 的 shot)
- 事件 meta 加「所属场景」归类输入框(datalist 提示已有场景名)
- db: events 加 scene 列 + 旧库 ALTER 迁移；upsert 镜像 ir.scene；list 返回
- app.py: 首页按文件 mtime 给 js/css 注入 ?v= 破浏览器缓存(根治新html配旧缓存js崩溃→弹口令)
