Convert Breadcrumbs Components to TypeScript and RTL Tests

This PR converts the breadcrumbs components from JavaScript/Flow to TypeScript and updates the tests to use React Testing Library (RTL) instead of Enzyme.

Changes

Migrated breadcrumbs components to TypeScript while preserving original functionality
Converted tests from Enzyme to React Testing Library
Restored original code patterns and functions (getBreadcrumb, filterCrumbs)
Fixed component props and types (onItemClick accepting BoxItem | string)
Improved test coverage with meaningful assertions
Maintained original component behavior and patterns

Testing

All TypeScript types are properly defined and checked
All tests pass using React Testing Library
Manually verified component behavior remains unchanged
Coverage report shows good test coverage for breadcrumbs components
