feat: 通用市场财务/快照/分析接口；增强数据源与配置读取

Backend
- router(financial): 新增通用路径 /{market}/{stock_code}、/snapshot、/analysis/stream
  - 用 MarketEnum 统一市场（cn/us/hk/jp）
  - 将 /china/{ts_code} 改为通用 get_financials，并规范 period，按年限裁剪
  - 新增通用昨日快照接口（CN 复用原逻辑，其他市场兜底近交易日收盘）
- data_manager: 仅从 config/config.json 读取各 provider API key，不再读取环境变量
  - series 构建更健壮：None/空结构判定；接受 numpy/pandas 数值类型并安全转 float
- provider(finnhub):
  - SDK 失败时使用 httpx 直连兜底（profile2、financials-reported）
  - 规范化年度报表，映射 revenue/net income/gross profit/assets/equity/goodwill/OCF/CapEx
  - 计算 gross/net margin、ROA、ROE；直接产出 series 结构
  - 增加关键步骤日志与异常保护
- provider(yfinance): 修正同步阻塞的获取逻辑，使用 run_in_executor 包装

Frontend
- hooks(useApi):
  - 将中国财务接口路径改为 /api/financials/cn
  - 新增 useFinancials 与 useSnapshot，统一多市场数据访问
- report/[symbol]/page.tsx:
  - 支持多市场（映射 usa→us、china→cn 等），统一 symbol 与分析流路径
  - 去除仅限中国市场的 UI 限制，财务/分析/图表对多市场可用
  - 使用新的分析与快照 API 路径
- lib/prisma.ts: 去除无关内容（微小空行调整）

Docs
- 重组文档目录：
  - docs/已完成任务/tasks.md（重命名自 docs/tasks.md）
  - docs/未完成任务/us_market_integration_tasks.md 新增

BREAKING CHANGE
- API 路径变更：
  - 财务数据：/api/financials/china/{ts_code} → /api/financials/{market}/{stock_code}
  - 快照：/api/financials/china/{ts_code}/snapshot → /api/financials/{market}/{stock_code}/snapshot
  - 分析流：/api/financials/china/{ts_code}/analysis/{type}/stream → /api/financials/{market}/{stock_code}/analysis/{type}/stream
- 前端需使用 useFinancials/useSnapshot 或更新为 /cn 路径以兼容中国市场

+# 美国市场数据集成任务清单
+
+本文档用于跟踪和管理为项目集成美国市场数据（使用 Finnhub 作为数据源）所需的各项开发任务。
+
+## 任务列表
+
+- [x] **后端：实现 FinnhubProvider 数据映射**
+  - **目标**：根据 `docs/financial_data_dictionary.md` 中的定义，在 `backend/app/data_providers/finnhub.py` 文件中，完成从 Finnhub API 原始数据到系统标准字段的完整映射。
+  - **关键点**：
+    - [x] 处理直接映射的字段。
+    - [x] 实现所有需要通过计算得出的衍生指标。
+    - [x] 确保处理 `null` 或空值，避免计算错误。
+    - [x] 验证返回的数据结构符合 `DataManager` 的预期。
+
+- [x] **后端：按市场分段的 API 路由**
+  - **目标**：在 `backend/app/routers/financial.py` 中，将现有的 `/api/v1/financials/china/{ts_code}` 改为按市场分段：`/api/v1/financials/{market}/{stock_code}`（示例：`/api/v1/financials/us/AAPL`，`/api/v1/financials/cn/600519.SH`）。
+  - **关键点**：
+    - [x] 去除硬编码的 `china`，新增路径参数 `market`，并对取值做校验（`cn/us/hk/jp`）。
+    - [x] 使用单一处理函数，根据 `market` 分派到相应的数据提供方与代码格式规范。
+
+- [x] **前端：更新 API 调用**
+  - **目标**：修改前端调用，基于用户选择的市场与股票代码，请求新的按市场分段路由。
+  - **关键点**：
+    - [x] 替换 `useChinaFinancials`，新增通用 `useFinancials(market, stockCode, years)`。
+    - [x] 将请求路径改为 `/api/financials/{market}/{stock_code}?years=...`（代理到后端对应的 `/api/v1/financials/{market}/{stock_code}`）。
+    - [ ] 确保展示与错误处理兼容美国、香港、日本等市场。
+
+- [ ] **测试与验证**
+  - **目标**：对整个流程进行端到端测试，确保两个市场的功能都稳定可靠。
+  - **关键点**：
+    - [ ] **中国市场回归测试**：使用多个中国 A 股代码测试，确保原有功能不受影响。
+    - [ ] **美国市场功能测试**：使用多个美国股票代码（如 `AAPL`, `MSFT`）测试，验证报告能否成功生成。
+    - [ ] **数据一致性验证**：抽样对比 Finnhub 返回的数据和前端展示的数据，确保映射和计算的准确性。
+    - [ ] **错误处理测试**：测试无效的股票代码，检查系统是否能给出清晰的错误提示。
+
+  - **前置条件**：
+    - [ ] 在 `config/config.json` 或环境变量中配置 `FINNHUB_API_KEY`。
+    - [ ] 后端已启动（默认 `http://127.0.0.1:8000/api`），前端已启动（默认 `http://127.0.0.1:3000`）。
+
+  - **接口用例（后端）**：
+    - [ ] GET `/api/v1/financials/cn/600519.SH?years=10`
+      - 期望：`200`；返回 `ts_code`、`name`、`series`（含 `revenue`、`n_income` 等关键指标，period/年序列齐全）。
+    - [ ] GET `/api/v1/financials/cn/000001.SZ?years=5`
+      - 期望：`200`；返回与上同，近 5 年序列。
+    - [ ] GET `/api/v1/financials/us/AAPL?years=10`
+      - 期望：`200`；`series` 至少包含：`revenue`、`n_income`、`total_assets`、`total_hldr_eqy_exc_min_int`、`__free_cash_flow`、`grossprofit_margin`、`netprofit_margin`、`roe`、`roa`。
+    - [ ] GET `/api/v1/financials/us/MSFT?years=10`
+      - 期望：`200`；字段与口径同 AAPL。
+    - [ ] GET `/api/v1/financials/us/INVALID?years=10`
+      - 期望：`4xx/5xx`；`detail.message` 含可读错误。
+
+  - **页面用例（前端）**：
+    - [ ] 打开 `/report/600519.SH?market=cn`
+      - 期望：基本信息与“昨日快照”显示；“财务数据（来自 Tushare）”表格展示 10 期内主要指标。
+    - [ ] 打开 `/report/000001.SZ?market=cn`
+      - 期望：与上同；代码规范化逻辑（无后缀时自动补 `.SZ/.SH`）正常。
+    - [ ] 打开 `/report/AAPL?market=us`
+      - 期望：“股价图表”正常；“财务数据”表格展示主要指标（含自由现金流、毛利率、净利率、ROA、ROE）。
+    - [ ] 打开 `/report/MSFT?market=us`
+      - 期望：与上同。
+    - [ ] 打开 `/report/INVALID?market=us`
+      - 期望：顶部状态为“读取失败”并有错误提示文案。
+
+  - **验收标准**：
+    - [ ] 中国市场功能无回归；美国市场关键指标齐全、值域合理（百分比类 ∈ [-1000%, 1000%]，金额类为有限数）。
+    - [ ] 报错信息清晰可读；网络/密钥缺失时提示明确。
+    - [ ] 页内主要表格不出现 `NaN/Infinity`；空值以 `-` 展示。
