Subject: [PATCH 1/2] fix(data-loading): ensure correct API used for
 DATA_SRC.BAO_STOCK
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Fixes a bug where AkShare API was used when BaoStock was explicitly requested as the data source. The change ensures that CBaoStock is loaded for DATA_SRC.BAO_STOCK.

- Corrects API selection logic in CChan.GetStockAPI to choose BaoStock, not AkShare, when needed
- Prevents CChanException '最高级别没有获得任何数据' from failing with the wrong data reader/format
- Ensures future extension for custom or other stock APIs works as intended

This fixes running failures for BAO_STOCK data source settings.

Subject: [PATCH 2/2] refactor: unify stock API usage to CAkShare for BAO_STOCK
 data src

Standardizes stock API selection logic to consistently use AkShare
(CAkShare) instead of any BaoStock integration for the BAO_STOCK data
source, promoting uniformity and reducing configuration confusion. This
ensures reliable and predictable data loading behavior for all
workflow scenarios involving stock API selection.
