Lee Donghyun d88856c3fa test(common): add unit tests for class serializer interceptor ...

Add comprehensive unit tests for ClassSerializerInterceptor which
previously had no test coverage despite being a public API.

Test coverage includes:
- constructor with custom transformer package injection
- intercept() with RxJS pipe and context options merging
- serialize() for arrays, objects, and StreamableFile handling
- transformToPlain() with type conversion and instanceOf checks
- getContextOptions() with metadata precedence (handler > class)
- Edge cases: null/undefined, mixed arrays, Date objects, primitives

Total: 25+ test cases covering all public methods and edge cases.
