refactor: remove unused components and clean up evaluation client

- Deleted CreateSkillForm and ProfileForm components as they are no longer needed.
- Removed the initializeEmptyEvaluation method from EvaluationClient, as the backend handles evaluation creation.
- Updated exports in evaluation index to reflect the removal of WelcomeEvaluationScreen.
