fix: correct BaseAgent initialization parameters in ModelDayExecutor

Fixed incorrect parameter passing to BaseAgent.__init__():
- Changed model_name to basemodel (correct parameter name)
- Removed invalid config parameter
- Properly mapped all configuration values to BaseAgent parameters

This resolves simulation job failures with error:
"BaseAgent.__init__() got an unexpected keyword argument 'model_name'"

Fixes initialization of trading agents in API simulation jobs.
