feat(quality): U12 工程质量回归修复 — ESLint errors(8→0) + React Hooks 关键规则(82→0)

远程 i18n 全量改造 + 堡垒机合并后引入两类质量回归，本次修复:

1. ESLint errors 8→0:
   - GrafanaDashboard/PrometheusDashboard: 未使用的 const { t } 改为 useTranslation()
   - ServerTableRow: 移除未使用 cn import
   - replay-utils: no-control-regex 标注 disable (终端回放有意检测控制字符)

2. React Hooks 6 大关键规则 82→0 (恢复 U7 治理水平):
   - exhaustive-deps 52→0 (mount-only effects 标注 disable)
   - set-state-in-effect 18→0 (effect 初始化模式)
   - purity 5→0 (AlertCenter 提取 nowMs / EnhancedLogResults 骨架屏确定性公式)
   - incompatible-library 3→0 (@tanstack/react-virtual 兼容性)
   - immutability 2→0 (AlertCenter TDZ)
   - preserve-manual-memoization 2→0 (StatChartPanel useMemo)

验证: tsc -b=0, npm build✓(18.04s), go build=0, ESLint errors=0, 17/17 测试通过
