Update AS path display to show handles with clickable links

- Change AS path from descriptions to handles (short names)
- Make each AS in the path a clickable link to /as/<asn>
- Add font-weight to AS links in path for better visibility
- Prevent word wrapping on all table columns except AS path
- Remove unused maxASDescriptionLength constant
