Fix integer comparison safety issues (6 HIGH priority)
Added parameter expansion with defaults to prevent comparison errors
on potentially empty variables:
- live-attack-monitor-v2.sh: IPSET_CREATE_EXIT, IPTABLES_EXIT
- live-attack-monitor.sh: IPSET_CREATE_EXIT, IPTABLES_EXIT
- malware-scanner.sh: START_EXIT
- email-diagnostics.sh: check_type, account_found
Pattern: Changed "$VAR" to "${VAR:-default}" in integer comparisons
to ensure safe comparisons even if variable is unexpectedly empty.
