Enable GraphQL introspection and simplify config

Register the GenericExceptionResolver as a Spring @bean and remove the custom GraphQlSourceBuilderCustomizer and GraphQLExecutionInstrumentation usage. Also enable schema introspection via application.properties (spring.graphql.schema.introspection.enabled=true). These changes simplify GraphQL configuration and ensure schema introspection is turned on through properties rather than a programmatic customizer.
