Major performance and storage improvements

- live-attack-monitor.sh: Remove snapshot loading, fix Apache log monitoring, add IP file sync for auto-blocking
- bot-analyzer.sh:
  * Implement gzip compression for large temp files (10-20x space savings)
  * Move temp files from /tmp to toolkit/tmp directory
  * Prevents filling up system /tmp on large servers
- run.sh: Add HISTFILE fallback to prevent crashes when sourced
- user-manager.sh:
  * Initialize TEMP_SESSION_DIR to fix user indexing errors
  * Remove unnecessary temp file I/O for faster user indexing
