Validates that the provided traderEnumValue exists in the Traders enum. If the value is valid, it returns the same enum value, effectively serving as a trader ID; otherwise, it logs an error and returns an empty string. This method provides a runtime check to prevent undefined behavior when using the enum as a dictionary key.

For example, instead of this: const traderId = Traders[Traders.PRAPOR];

You can use safely use this: const traderId = this.traderHelper.getValidTraderIdByEnumValue(Traders.PRAPOR);
