Improve CHECK 32 menu detection accuracy

Issues Fixed:
1. Pattern too strict - only accepted "Back to Main Menu|Exit"
   Now accepts any "Back" or "Exit" text (e.g., "Back to Backup Menu")

2. False positives on handle_*_menu() functions
   These are event handlers, not menu display functions
   Now only checks show_*_menu() functions

Changes:
- Relaxed pattern: (Back to Main Menu|Exit) → (Back|Exit)
- Removed handle_.*_menu() from detection (handlers don't display menus)
- Updated grep to only find show_.*_menu() functions

Result: Fewer false positives, catches real menu standard issues
