refactor(i18n): U19 i18n hash 键治理 — 删除 866 死键 + 重命名 21 高频键

死键清理: 从 zh-CN.json 和 en-US.json 移除 866 个重构遗弃的 unreferenced
hash keys (filename.hash 格式)。这些键在组件迁移到语义化键后成为孤儿。

Live 键重命名 (21 个):
  ui.datatable.s1a2b3c4d → selectedCount
  ui.datatable.s2b3c4d5e → columns
  ui.datatable.s3c4d5e6f → totalCount
  aiops.predictive.s{1-3} → metricsTab/capacityTab/costTab
  aiops.predictivecost.s{1-3} → aiFailed/overview/aiInsight
  task.systemtaskspanel.s{1-3} → monitor/cleanup/finops
  aiops.agentcli.s{1-3} → archLayer/archDesc/securityLayer
  system.useldapmanageme.s{1-2} → ouExists/createOuFailed
  common.requestts.sd3ab821c → common.request.tokenExpired
  k8s.editAdvanced.s0c1fec65 → secondsPlaceholder
  k8s.{kubectl,podExec}.sc8107726 → connectErrorAnsi

影响: zh/en 7597→6731 keys 对齐, 文件 328KB→276KB (-16%)
      仍有 172 个 live hash keys 待后续重命名
