Show AS descriptions in AS path on prefix detail page

- Display AS descriptions alongside AS numbers in format: Description (ASN)
- Truncate descriptions longer than 20 characters with ellipsis
- Increase container max width to 1600px for better display
- Enable word wrapping for AS path cells to handle long paths
- Update mobile responsive styles for AS path display
