fix(def/ui): 验收审计补丁——调试弹窗内置变量口径与 chips 区分；分组态空 flowGuid 兜底

- ExprEvalModal：内置变量条 submitterId 改显真实 id（原用 submitterName 冒充，用户照抄进
  样例 JSON 会填错类型）；可用变量 chips 区分内置变量（灰底，对齐原型 .chip.bt）并让手动模式
  同样提供内置键（原型 S5「内置变量同款可插」）；chips 去重，避免 formData 键与内置键同名重复。
- Defs：分组视图空 flowGuid 行不再被整体丢弃，各自单列一行；openMap 改用合成 key（__noguid__{id}）
  防止与其他行共用 "" 键互相牵连；GUID 列空值显示「—」。
- 验证：npm run build 通过（1m16s，产物含 Defs / ExprEvalModal chunk）；
  npx tsc --noEmit 48 条与既有基线完全一致、本次改动文件 0 条。
