Solaris /usr/bin/grep has no -A ("illegal option -- A"), so _getAKI
printed an error to stderr on every cron renewal and returned empty.
The empty AKI silently corrupts the RFC 9773 ARI certID, so ARI is
never available and renewal falls back to the fixed schedule.
Split the pipeline into a testable stdin filter _extractAKI and select
the value line with a portable sed range instead.
Same fix for the two hooks that still used grep -A: dns_world4you.sh
(also replaces the GNU-only "\s" in the same expression) and
deploy/keyhelp.sh (the -A 2 window could truncate the div range that
follows it, so it is just dropped).
