feat(v0.2): 双击价格创建点位监控 + 分钟K补齐修复 + 超时设置独立

点位监控（双击图表）:
- 日K/单日分时/多日分时价格主图支持双击, 自动预填目标价并按最新价判断上穿/下穿
- 成交量区与指标子图不触发; 自动生成通知文案, 用户手改后不再覆盖
- 已启用点位监控以横虚线显示 (上穿红/下穿绿), 并纳入三图 Y 轴范围
- 复用现有 PriceAlertDialog, 未改变后端 close>=/<= 规则语义与冷却机制

分钟K数据:
- 个股补齐强制回溯请求天数 (force_full_days), 修复切换日期范围只显示3天
- 单股并发补齐复用仓库写锁, 修复 Windows Parquet 临时文件替换失败
- DuckDB 读路径改用短生命周期 cursor, 释放对 Parquet 文件的占用

设置页:
- 数据任务超时从 DataSources 抽出为独立"超时设置"页签
- 设置侧栏垂直居中

验证: pytest 38 passed, pnpm build ok, git diff --check ok, 浏览器端到端 GUI 验证通过
