Add score color logic and evaluation migration

- Introduced `getScoreColors` function to dynamically set badge colors based on skill scores for better visual feedback.
- Updated HomePage to display skill evaluation percentages with corresponding colors.
- Implemented `migrateEvaluation` function to ensure existing evaluations are updated with new skill categories, enhancing data integrity.
- Refactored data loading in `loadSkillCategories` and `loadTeams` to fetch from API endpoints, improving flexibility and maintainability.
