feat(story): 完成故事016.003 - 搬迁数据处理函数到独立模块并添加类型定义

- 创建 data-processing 模块，包含5个文件：
  - series-calculator.ts: 系列数据处理函数(369行)
  - axis-calculator.ts: 坐标轴计算函数(595行)
  - categories-calculator.ts: 分类数据处理函数(132行)
  - tooltip-calculator.ts: 提示框数据计算函数(175行)
  - index.ts: 统一导出文件(65行)
- 成功搬迁14个数据处理函数并添加完整TypeScript类型注解
- 类型检查通过(pnpm typecheck)
- 构建成功，所有文件正确生成到dist目录
- 更新史诗016进度，故事016.003标记为Ready for Review
