feat(data): 财务/日线同步增量 + 新浪「两边一致」校验兜底 + 逐只进度

- financial 默认增量：按 A 股披露节奏判断已最新并跳过；--full 强制全量重拉
- Tushare fina_indicator 增加报告期窗口与 100 条/请求自动分页（修复老报告期静默截断）
- 新浪兜底收紧为校验兜底：两源重叠历史一致才导入缺失键，行标记 source=sina；
  财务可比字段取 eps/销售毛利率（ROE 两端口径不同不作依据），日线只比较最近重叠交易日
- CLI 输出逐只进度与导入内容描述（来源/行数/报告期与公告区间），失败股票留待重跑
- financial_indicator 增 source 列（迁移 d3f6c9a21b04）；新增一致性/分页/服务测试
