docs: hard-wrap pre-existing long prose lines to satisfy doc-linter

scripts/doc-linter.py enforces an 80-character limit outside fenced code
blocks and treats any finding as a failure. Wrap long paragraphs in
files that this PR touched so CI passes:

- docs/configuration/protocols/ospf.md: wrap the WireGuard cost note.
- docs/configuration/protocols/traffic-engineering.md: wrap the IS-IS/
  OSPF note.
- docs/contributing/debugging.md: wrap the Phabricator paragraph, and
  guard the long [bootchart.conf]/[vyatta-cfg] link references at EOF
  with `% stop_vyoslinter`/`% start_vyoslinter`.
- docs/vpp/configuration/ipsec.md: wrap the integration, requirements,
  algorithm, ACL, VTI example, troubleshooting paragraphs.

Pure reformatting; no semantic changes.
