fix(newos4): document curl in help command table (auto)

Plan: .hermes/plans/2026-11-07_061825-newos4-curl-help-row.md (T1)
Root cause: curl shipped in v4.6.151 (cryptogzip.js:19 getHelpInfo,
:612 commands['curl']) but help.html's command table was never updated,
so check_help_coverage() reported 365/366.

Change: one <tr> row added after the wget row in help.html's command
table. No JS/PHP touched; cryptogzip.js, modules-index.json and atlas
unchanged as specified in T2.

Verification:
  grep -c '<code>curl ' help.html          -> 1
  wget row at 1086, curl row at 1087       -> adjacent
  grep -c "_isBase64" modules/ext/cryptogzip.js -> 0 (unchanged)
  git diff --stat                          -> help.html | 1 +
  python3 scripts/newos4-maintain.py       -> PASS: help coverage 366/366,
                                              maintenance result: OK,
                                              needs OK: none
  HTTP help.html                           -> 200
