refactor(i18n):Refactoring I18nBaseException from Java to Kotlin

- Convert the I18nBaseException class from a Java file to a Kotlin file
- Optimized Kotlin syntax for class definitions and constructors
- Use val to get property values
- Added @Transient annotation to replace transient keywords in Java
