Add cleanup script for IP reputation and toolkit data

Created comprehensive cleanup tool to remove all server-specific data
before transferring toolkit to another server.

NEW FILE:
- modules/maintenance/cleanup-toolkit-data.sh
  * Removes IP reputation database (/var/lib/server-toolkit/)
  * Cleans all temporary analysis files (/tmp/*bot*, *500-tracker*, etc.)
  * Removes generated reports
  * Clears cache and session data
  * Optional log file removal
  * Shows summary of items removed and space freed
  * Safety confirmation required before cleanup

UPDATED:
- launcher.sh
  * Added cleanup script to Backup & Recovery menu (option 9)
  * Placed in "Data Management" section
  * Clearly marked with trash icon to indicate destructive operation

PURPOSE:
This ensures the IP reputation database and other server-specific data
are not transferred when moving the toolkit between servers. Each server
should build its own IP reputation database based on its own traffic and
attack patterns.

USE CASES:
✓ Moving toolkit to different server
✓ Starting fresh analysis
✓ Removing server-specific data before sharing toolkit
✓ Regular maintenance/cleanup

WHAT GETS CLEANED:
- /var/lib/server-toolkit/ip-reputation/ (IP reputation database)
- /tmp/bot_analysis_* (bot analyzer temp files)
- /tmp/500-tracker-* (error tracker temp files)
- /tmp/live-monitor-* (live monitoring temp files)
- /tmp/*_report_*.txt (generated reports)
- /var/cache/server-toolkit/ (cached data)
- Session/lock files
- Optional: execution logs
