feat: 选股器重构 V2 — 概念板块/多行业地域/PS/布林带均线/北向资金

[Copilot]

选股器已有基础多维度筛选，但未利用项目后续接入的概念板块、北向持仓、技术因子等数据源。本次重构扩展筛选维度并增强返回数据。

新增筛选维度

• 概念板块 (conceptCodes: string[]) — INNER JOIN ths_index_members 按同花顺概念板块多选过滤
• 多行业/多地域 (industries/areas: string[]) — 升级为数组，SQL ANY() 匹配，向后兼容旧单选字段
• PS(TTM) (minPsTtm/maxPsTtm) — 利用已有 stock_daily_valuation_metrics.ps_ttm
• 布林带信号 (bollSignal: 'above_upper' | 'below_lower' | 'squeeze')
• 均线趋势 (maTrend: 'bullish' | 'bearish') — 使用 boll_mid 近似 MA20 + MACD DIF 方向
• 北向资金 (northboundOnly: boolean) — INNER JOIN LATERAL hk_hold_detail 最新持仓

新增端点

• POST /stock/screener/concepts — 返回同花顺概念板块列表（24h Redis 缓存），供前端下拉多选

返回字段增强

• psTtm: number | null — 市销率 TTM
• concepts: string[] | null — 所属概念板块名称列表（批量查询，避免 N+1）

新增排序字段 & 内置预设

排序新增 PS_TTM、CLOSE。预设新增 4 个：北向重仓、技术突破、超跌反弹、低PS高成长。

概念名称批量查询示例

// 对返回结果集批量查询概念，降级容错
const conceptRows = await this.prisma.$queryRaw<ConceptRow[]>`
  SELECT tm.con_code AS "conCode", ti.name
  FROM ths_index_members tm
  JOIN ths_index_boards ti ON ti.ts_code = tm.ts_code
  WHERE tm.con_code = ANY(${tsCodes}) AND tm.is_new = 'Y' AND ti.type = 'N'
`

其他

• 数组字段均加 @ArrayMaxSize() 防止过大查询
• 布林带缩口阈值提取为 BOLL_SQUEEZE_THRESHOLD 常量
• 设计文档 docs/design/选股器重构-后端设计.md
• 39 个单元测试覆盖全部新增逻辑

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• checkpoint.prisma.io
  • Triggering command: /opt/hostedtoolcache/node/24.14.1/x64/bin/node /opt/hostedtoolcache/node/24.14.1/x64/bin/node /home/REDACTED/work/server-code/server-code/node_modules/prisma/build/child {"product":"prisma","version":"6.19.2","cli_install_type":"local","information":"","local_timestamp":"2026-04-18T03:40:52Z","project_hash":"230dd102","cli_path":"/home/REDACTED/work/server-code/server-code/node_modules/.bin/prisma","cli_path_hash":"5a210d3d (dns block)
  • Triggering command: /opt/hostedtoolcache/node/24.14.1/x64/bin/node /opt/hostedtoolcache/node/24.14.1/x64/bin/node /home/REDACTED/work/server-code/server-code/node_modules/prisma/build/child {"product":"prisma","version":"6.19.2","cli_install_type":"local","information":"","local_timestamp":"2026-04-18T03:41:03Z","project_hash":"230dd102","cli_path":"/home/REDACTED/work/server-code/server-code/node_modules/.bin/prisma","cli_path_hash":"5a210d3d (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

目前项目已经新增了很多功能也接入了很多新的数据，你研究一下整个项目，然后输出选股器的重构方案，让选股器这个功能更加强大好用
