Fix double slash issues in library page URL generation (#1485)

- Fix URL construction in library.py to handle empty prefix correctly
- Fix get_component_link function to avoid double slashes when prefix is empty
- Fix category overview links to handle empty prefix properly
- Fix library preview page URL generation

This resolves 404 errors on library component links caused by URLs like /docs/library//data-display
