Fix: Resolve GraphRecursionError by passing config params to agents and increasing recursion_limit to 200

- Pass max_debate_rounds and max_risk_discuss_rounds from config to ConditionalLogic
- Pass max_recur_limit from config to Propagator
- Increase default recursion_limit from 100 to 200 in default_config.py
- Increase Propagator default max_recur_limit from 100 to 200

Also includes earlier fixes:
- Add 365-day minimum date range validation to get_stock_data tool
- Update market analyst prompt to specify 1-year data requirement
- Initialize all debate state fields (bull_history, bear_history, judge_decision, etc.)
- Add report completeness logging in trading_service.py
- Add debug logging in frontend results page
