Fix 22 critical runtime errors from 'local' keyword used outside functions

Removed 'local' keyword from script-level variable declarations in:
- website-error-analyzer.sh (8 instances)
- wordpress-cron-manager.sh (3 instances)
- live-attack-monitor.sh (3 instances)
- live-attack-monitor-v2.sh (3 instances)
- acronis-uninstall.sh (3 instances)
- malware-scanner.sh (1 instance)
- acronis-troubleshoot.sh (1 instance)
- diagnostic-report.sh (1 instance)

The 'local' keyword can only be used inside bash functions.
Using it at script-level causes immediate runtime errors.
