fix(crawler): runGenericScript 支持 DB keywords, 跟 runPowerChina 对齐

【问题】
runGenericScript() 直接 execSync 没拼 --keyword, 导致 DB CrawlerConfig.keywords
对新矿/中核等 generic python 脚本完全失效. 之前 7 月份排查中电建入库少时确认过:
- 中电建: runPowerChina() 会逐 keyword 调用 → DB 关键词生效
- 新矿/中核: runGenericScript() 只调用一次不传 keyword → DB 关键词沦为摆设,
  新矿实际是全量抓"寻源公告", 入库量看起来正常但跟 DB 配置不一致

【修复】
照搬 runPowerChina() 的 keyword 循环+去重模式:
- 解析 config.keywords (JSON), 为空默认 ['']
- 逐个 keyword 调用 execSync, 失败继续下一个
- 用 seen Set 跨 keyword 去重
- 只处理 downloaded_at 是今天的记录 (避免历史重复入库)

【验证(生产)】
- 部署后 health 200 OK
- 手动跑 fetch-xkgroup.py --keyword 电缆/钢材/阀门/管材, 4 个全部 0 命中
  (新矿寻源公告确实没有电缆/钢材等关键词)
- 关键词确认生效, 新矿后续入库量会大幅下降 (按 DB 关键词配置真实反映)
