Socket: 🔧 Migrating the Socket Module from Java to Kotlin

[psychology50]

작업 이유

I have been working on partially migrating the Socket Module from Java to Kotlin.
This migration was initiated to take advantage of Kotlin's features, which I believe will be particularly beneficial for handling real-time connections in the socket module.

작업 사항

• Partially converted Java code to Kotlin to improve code stability and readability.
• Enhanced authentication/authorization result processing by introducing the EvaluationResult sealed interface in the PreAuthorizeSpELParser.
• Applied functional programming principles to make the code flow more explicit.
• Leveraged Kotlin's null safety to eliminate potential NullPointerException issues.

• Ensure interoperability between Java and Kotlin is well-maintained.
• Verify that Kotlin-specific features (e.g., sealed interfaces, extension functions) are used appropriately.
• Check that existing functionality continues to work as expected.
• Review error handling and logging to ensure they are implemented properly.
• Confirm that the code style aligns with the project's standards.
