Fix menu standards: Add RED 0 back buttons to remaining 6 menus

Fixed bot-analyzer.sh (2 menus):
1. show_post_analysis_menu: Changed '3) Go Back' to '0) Back' with RED
2. show_action_menu: Changed '0) Go Back' to '0) Back' with RED

Fixed malware-scanner.sh:
- show_scan_menu: Changed '0. Back to main menu' to '0) Back' with RED

Fixed live-attack-monitor.sh (2 menus):
1. show_blocking_menu: Changed '0) Cancel' to '0) Back' with RED
2. show_security_hardening_menu:
   - Changed 'q) Return to Monitor' to '0) Back' with RED
   - Updated case handler to use '0' instead of 'q|Q'

Fixed acronis-logs.sh:
- show_log_menu: Changed '0) Return to Menu' to '0) Back' (already had RED)

All 9/9 menus now use consistent RED 0 back buttons with 'Back' or 'Exit' text
