fix: resolve linting errors in tree visualizations

- Fix 'current' variable reassignment in BTreeVisualization.tsx
- Remove unused 'error' parameter in catch block
- Remove unnecessary dependency 'setRecoloringNodes' in RedBlackTreeVisualization.tsx
- All critical linting errors resolved, only minor warning remains
