feat(api): 集成 json-bigint 处理大整数精度问题

- 添加 json-bigint 和 bignumber.js 依赖用于处理超出 JavaScript 安全范围的整数
- 创建 src/utils/jsonBig.ts 提供 safeJsonParse 与 safeJsonStringify 方法
- 新增 src/api/request.ts 封装请求逻辑，自动注入 Authorization header 并解析响应数据
- 在 src/api 目录下多个文件中将 uni.request 替换为封装后的 request 方法
- 更新 package.json 添加相关依赖及类型定义
- 添加 types/json-bigint.d.ts 以支持 TypeScript 类型检查
- 修改页面组件中部分直接调用 uni.request 的地方为 request 方法
- 优化 uploadAvatar 中的数据解析逻辑以兼容大整数字段

+# json-bigint 集成说明
+
+## 1. 安装
+
+建议使用 cnpm 安装：
+
+```powershell
+cnpm install json-bigint --save
+```
+
+> 说明：这个仓库的 `package.json` 已经添加了 `json-bigint` 依赖，执行上面命令会安装依赖并写入 lock 文件。
+
+## 2. 类型定义
+
+项目内已添加 `types/json-bigint.d.ts`，用于在 TypeScript 中声明模块类型。无需额外安装 @types。
+
+## 3. 使用方法 / 配置点
+
+1. 项目中已创建 `src/utils/jsonBig.ts`，提供 `safeJsonParse` 与 `safeJsonStringify` 方法，内部使用 `json-bigint` 的 `storeAsString: true` 选项来保证大整数不会丢失精度。
+2. 建议通过 `src/api/request.ts` 中的 `request` 封装替代直接调用 `uni.request`。`request` 封装会注入 `Authorization` header（如果本地 token 存在）并对返回的 `response.data` 做 `json-bigint` 解析，返回解析后的对象。
+3. 若某些上传（`uni.uploadFile`）或下载接口返回的 `data` 字段也可能包含大整数，请在对应回调中使用 `safeJsonParse` 解析。
+
+## 4. 迁移指南
+
+把项目中直接调用 `uni.request(...)` 的地方替换为 `request(...)`：
+
+- 例子：
+  - 从 `uni.request({ url: '...', method: 'POST', data: {...} })`
+  - 迁移为 `request({ url: '...', method: 'POST', data: {...} })`
+
+`src/api` 下已经示例修改了 `user.ts` 与 `heartRate.ts`，其余模块可按需迁移。
+
+## 5. 注意事项
+
+- `storeAsString: true` 会把超过 JS 安全整数范围（> Number.MAX_SAFE_INTEGER）的数字转为字符串保存在 data 中。如果你希望得到 BigInteger 可使用 `jsonbig({ storeAsString: false })` 并接收 BigNumber 类型（jsbn），但那会改变使用方式。
+- 请根据后端返回策略选择 `storeAsString` 配置。
+
+---
+如果需要我把项目中所有 `uni.request` 调用都替换为 `request`（自动化修改），我可以继续批量替换。
