fix(display): 证据金额去尾零与界面显示修复

- 证据接口与 CSV/XLSX 导出去掉 NUMERIC(44,24) 存储尺度尾零（无损精度）
- KPI 大金额折行截断：字号收紧 + nowrap + 省略号兜底
- 贡献分解/走势图表轴标签重叠与 Y 轴裁剪：hideOverlap + 万/亿缩写
- 表格隐藏全不可用指标列，空态改为条件渲染（修复空表覆盖层残留）
- 数据质量与字段字典/导入确认的中文标签映射（不再暴露内部键名）
- 证据弹窗重复点击当前期间停在加载中（F03）；证据表格最小宽度
- Playwright 覆盖 F03 重复点击与期间切换场景

+
+## Stack and verification
+
+- Django 5.2 后端（PostgreSQL 生产 / SQLite 仅开发），金额一律 `NUMERIC(44,24)` + Python `Decimal`（精度 60）；JSON 中金额为字符串。
+- React 19 + TypeScript + Vite 前端（AG Grid、ECharts），`npm run build` 含 `tsc --noEmit`。
+- openpyxl 流式生成公式工作簿（SUMIFS/COUNTIFS），公式正确性靠 LibreOffice 无头重算验证。
+- pytest（`--cov-fail-under=85`）+ Playwright E2E；CI 在 PostgreSQL 17 服务容器上跑全量。
+- 验证命令：`uv run pytest`、`uv run ruff check server finance tests scripts`、`npm run typecheck`、`python manage.py makemigrations --check`。
+
+## Review priorities
+
+1. **金额精度**：财务计算、持久化、Excel 公式生成路径上出现 `float()`、`round()`、Decimal 与 float 混算、或金额以数字（非字符串）进 JSON，必须报。浏览器 `Number` 只允许用于绘图与显示。
+2. **缺失值语义**：成本/毛利/人数等依赖字段缺失时必须传播为不可用（服务端 `None`、Excel `#N/A`），不得静默转 0 或跳过；比率分母为零/非正同样不可用。对账容差按指标类型独立（人数严格相等、金额 0.01、比率 0.0001），不得为消除报错统一放宽容差。
+3. **文件与路径安全**：清理/下载/回收文件前必须 `lstat` 校验且拒绝符号链接（目录用 `O_NOFOLLOW` 打开），只删除本次任务在受控目录内创建的文件；清理失败要留日志与可追踪状态，不得静默吞掉 `OSError`。
+4. **越权与生命周期**：每个 endpoint 必须声明 roles 白名单；worker 执行阶段要重新核验角色、`is_active`、组织与科室范围（不能只信创建时的检查）；卡死任务要有超时恢复，且恢复不得与活跃 worker 抢任务。
+5. **事务与并发**：配额/唯一性检查必须在事务内并锁定稳定的所属行（如 Membership），审计与业务变更同事务提交；乐观并发用 revision + 409，不得静默后写覆盖。
+6. **Excel 公式注入与上限**：不可信文本写入单元格必须强制文本类型；CSV/公式中 `= + - @` 开头加 `'` 前缀；SUMIFS/COUNTIFS criteria 必须转义 `~ * ? "` 并检查 255 字符上限、公式 8192 字符上限。
+7. **前端异步状态**：useEffect 依赖未变时不得清空已加载数据（同状态重复点击不能停在“加载中”）；并发请求要有过期响应丢弃（active flag/AbortController）；失败路径要有可见错误与重试。
+8. **测试真实性**：行为修复必须带“修复前失败、修复后通过”的回归测试；环境门禁（LibreOffice、PostgreSQL 并发、真实 AI）必须显式 skip 并注明原因，不得用 mock 通过冒充真实验收。
+
+## Avoid reporting
+
+- 纯格式与风格问题（ruff / prettier 已在 CI 把关）。
+- 改动行为已被等价集成测试或 E2E 覆盖时，仅因缺少同名单测而报缺测试。
+- 没有具体并发路径的假想竞态（SQLite 单写者语义下的理论交错不算，除非改动显式依赖 PostgreSQL 行为）。
+- 对 `docs/` 报告类 HTML/Markdown 的措辞与结构建议——它们记录的是验收状态，不是产品代码。

+# 对抗式 PR 审查：先一遍找出候选缺陷，再对每一条派一个反驳者去证伪它，只有
+# 活下来的才会发到 PR 上。这个不对称是刻意的——AI 审查员死于误报远早于死于漏
+# 报，所以反驳阶段默认站在"这是误报"一边，"什么都没发现"是可接受的结果。
+#
+# 引擎不在本仓库，在 vertai-tech/ai-review-engine。本文件只负责把三样东西摆到
+# 位再调它：被审查的代码、本仓库的审查侧重、引擎本身。
+#
+# 接入一个仓库需要（各一次）：
+#   1. 引擎仓库的 templates/ai-review.yml -> 本仓库 .gitea/workflows/ai-review.yml
+#   2. 引擎仓库的 templates/ai-review.md  -> 本仓库 .gitea/ai-review.md，按本仓库
+#      的技术栈改写
+#   3. 下面这些组织级机密 / 变量（组织设置 → Actions）配好之后，新仓库就不用再
+#      单独配任何东西：
+#        secret   REVIEW_API_KEY        模型网关的 key
+#        secret   REVIEW_ENGINE_TOKEN   只读 PAT，用于拉私有的引擎仓库
+#        variable REVIEW_BASE_URL       任意 OpenAI 格式的根地址
+#        variable REVIEW_MODEL          支持 function calling 的模型
+#
+# 自动修复默认是关的。要开，在**本仓库**的 设置 → Actions → 变量 里加一个（这两条
+# 都不要配到组织级，那样等于给所有仓库都开了），并在组织级配一次
+# REVIEW_FIX_MODEL：
+#   REVIEW_AUTOFIX=1            改代码、提交、推回 PR 分支
+#   REVIEW_FIX_SUGGEST_ONLY=1   只把改法写进评论，一个字节都不落盘
+# 两个都配的时候，不动仓库的那个赢。fork 来的 PR 推不回去，apply 会自动降级成
+# 只给改法。
+#
+# 默认只修一轮：修完推一个 commit，那次推送起的下一轮只审不改。要"一直修到没
+# 意见"，把仓库变量 REVIEW_FIX_ROUNDS 调大——它数的是这个分支已经被自动修过几
+# 轮，轮次写在提交消息里。
+#
+# 改法本身是两步定出来的：一个模型决定这条该不该由机器改、以及改完长什么样，另一
+# 个模型把它落成逐字命中的替换。想让这两步用不同的模型，就再配一个组织级的
+# REVIEW_FIX_PLAN_MODEL——判断那步值得用贵的，抄写那步不值得。不配也照样分两步，
+# 只是两步都用 REVIEW_FIX_MODEL。
+#
+# 成本由模型决定而不是由这个设计决定：同一个 PR 在便宜模型上是几分钱，在旗舰
+# 模型上是几美元。换模型前先看一眼那家的每 token 价格。
+# 换了模型记得同步组织变量 REVIEW_PRICES，缺单价的那轮评论不报金额。
