Move all persistent data to /tmp (no system pollution)

Moved from /var/lib/server-toolkit/ to /tmp/:
- Threat intelligence cache
- Whitelist IPs
- Attack pattern logs
- Incident reports
- Shared threat coordination logs
- Live monitor snapshots

Philosophy: Deleting toolkit directory should remove ALL data.
System directories (/var/lib/) caused stale data to persist.
Using /tmp/ ensures auto-cleanup on reboot and complete removal.
