feat(web): Chinese business annotations for all config page fields

- 新增 web/lib/config/fieldLabels.ts:字段→中文业务含义字典,注释原文取自
  规则包映射配置表.xlsx「字段注释」表与游走策略配置表.xlsx 数据字典行
  (权威来源,非编写);query prompts 字段含义取自 M2 brief 合同
- 配置页表头改为中文名+英文字段名+悬浮注释;每张表附「字段业务含义说明」
  折叠清单;dispatch/映射/binding/边目录补 notes 列,原因码表补业务解释列;
  Prompts 区字段行内带含义
