idle-check.sh: region is hard-coded to us-east-1 and ignores install-idle.sh --region #130

idle-check.sh L19 has REGION="us-east-1".

install-idle.sh accepts --region (L55) and writes all /openclaw/wake-config/* parameters in that region. But it copies idle-check.sh with no change (L347), and the systemd unit sets no region.

Problem: With --region eu-west-1, idle-check.sh reads SSM in us-east-1 and finds nothing. It also sends stop-instances to us-east-1. Idle shutdown does not work outside us-east-1.

Fix (one way):

• In idle-check.sh: REGION="${IDLE_REGION:-us-east-1}"
• In systemd/idle-check.service: add Environment=IDLE_REGION=${REGION}
• In the sed at install-idle.sh L352-354: add -e "s|\${REGION}|${REGION}|g"
