fix: Update .editorconfig and refactor SQLHelper registration

Updated .editorconfig with new style preferences and modified existing ones. Refactored Load method in SQLHelperModule.cs to use an expression-bodied member. Updated RegisterSQLHelper method in Register.cs to check for existing SQLHelper service before adding.
