fix: correct class name typos and variable naming issues

Fix critical typos in class names and variables that could cause confusion
and runtime errors.

Class name fixes:
- trandeVoter → TradeVoter (market_trade/core/trandeVoter.py)
- decsionManager → DecisionManager (market_trade/core/decisionManager_v2.py)
- coreSignalTrande → CoreSignalTrade (market_trade/core/signals_v2.py)
- coreIndicator → CoreIndicator (market_trade/core/indicators_v2.py)
- indicatorsAgrigator → IndicatorsAggregator (indicators_v2.py)
- signalsAgrigator → SignalsAggregator (signals_v2.py)
- riskManager → RiskManager (market_trade/core/riskManager.py)

Variable typo fixes:
- commision → commission (riskManager.py, lines 8-9, 24)
- probabilityDecsion → probability_decision (decisionManager_v2.py:84)

Type hint corrections:
- Fixed pd.DataFrame() → pd.DataFrame (incorrect syntax in 4 files)

Bug fixes:
- Fixed mutable default argument antipattern in indicators_v2.py:33
  (indDict={} → indDict=None)
- Fixed mutable default argument in CoreTradeMath.py:22
  (params={} → params=None)

All class references updated throughout the codebase to maintain
consistency.
