Refactor code to remove trailing whitespace and improve readability

- Cleaned up trailing whitespace in `games_controller.rb`, `game.rb`, and `validate_scenario.rb` to enhance code quality and maintain consistency across the codebase.
- Updated migration file `remove_unique_game_constraint.rb` to remove unnecessary whitespace, ensuring a cleaner migration history.
- Improved overall readability of the code by eliminating redundant blank lines in various files.
