* fix: replace deprecated pandas fillna(method=) with ffill()/bfill()
Replace deprecated fillna(method="ffill"/"bfill") calls with modern
pandas ffill() and bfill() methods to fix FutureWarnings in pandas 2.x.
Also includes black formatting fixes for compliance.
This addresses the pandas deprecation warnings portion of issue #1981.
Other issues (date parsing, type conversion, timezone handling) will be
addressed in separate commits.
Fixes:
- Yahoo collector: 2 instances in calc_change() and adjusted_price()
- BaoStock collector: 1 instance in calc_change()
- Core utils: resam.py fillna operations
- Backtest: profit_attribution.py stock data processing
- High-freq ops: FFillNan and BFillNan operators
- Position analysis: parse_position.py weight processing
Partially addresses GitHub issue #1981
