Subject: [PATCH] refactor: standardize DecisionManager, DealManager, and
 RiskManager
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Complete standardization of remaining core management classes.

DecisionManager method renames (camelCase → snake_case):
- getOnlineAns → get_online_answer
- getSignalsAns → get_signals_answer
- getRightAns → get_right_answer
- getRetroTrendAns → get_retro_trend_answer
- generateMatrixProbabilityFromDict → generate_matrix_probability_from_dict
- createDump → create_dump
- loadDump → load_dump

DecisionManager variable renames:
- sigDict → sig_dict
- signalsAns → signals_ans
- signalsDataDict → signals_data_dict
- retroTemplateDict → retro_template_dict
- reqSig → req_sig
- sigAns → sig_ans
- rightAns → right_ans
- dictSignals → dict_signals
- dataDict → data_dict
- fileName → file_name

RiskManager improvements:
- getDecision → get_decision
- probabilityDecision → probability_decision
- Added comprehensive docstrings
- Improved spacing and formatting

DealManager method renames:
- findDealByPriceAndFig → find_deal_by_price_and_figi
- openDeal → open_deal
- closeDeal → close_deal

DealManager variable renames:
- startPrice → start_price
- desiredDeal → desired_deal
- newDealDict → new_deal_dict
- newDeal → new_deal

Documentation:
- Added comprehensive Google-style docstrings to all classes
- Documented all public methods with Args, Returns, and Notes
- Added usage examples where applicable
- Removed wildcard imports, using explicit imports

Follows: PEP 8, Google Python Style Guide
