Refactor scenario JSON files for improved readability and consistency

- Consolidated array elements in scenario_903.json, scenario_904.json, scenario_905.json, scenario_906.json, scenario_908.json, scenario_910.json, scenario_911.json, scenario_912.json, and scenario_913.json to single-line format for better clarity.
- Removed unnecessary line breaks and whitespace in availableGeneralCommand and events sections across multiple scenario files.
- Ensured consistent formatting of event definitions, particularly for destroy_nation and OpenNationBetting events.
