docs(cli, aws): hard-wrap pre-existing long prose lines to <=80 chars

doc-lint regression on [vyos-documentation#2024](https://github.com/vyos/vyos-documentation/pull/2024): the CI workflow's
`scripts/doc-linter.py` scans every line of every changed file
(not just changed lines), so the typo fix on `cli.md:464` and the
capitalization fix on `aws.md:118` surfaced 57 pre-existing >80-char
violations that have lived on rolling since the MyST migration.

`cli.md` — 53 prose paragraphs hard-wrapped at word boundaries to
80 chars, preserving content fidelity. List items use hanging-indent
continuations under their `- ` marker. No content reworded; only
soft-wrap → hard-wrap.

`aws.md` — wrapped the inline AWS GWLB blog link (L164) and the
References section (L185-187) with `% stop_vyoslinter` /
`% start_vyoslinter` markers. These are URL-bearing lines that
cannot be shortened (URL itself >80 chars).

Verified locally:
`python3 scripts/doc-linter.py "['docs/cli.md','docs/installation/cloud/aws.md','docs/automation/terraform/terraformvyos.md']"`
→ exit 0, no violations.
