Alaa Kaddour 7095e755fa fix: replace deprecated pandas fillna(method=) with ffill()/bfill() (#1987 )

* 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
