FIXED:
- Added explicit validation that show_scan_menu() function exists before calling
- Added explicit validation that print_banner() exists before using it
- Added error output if print_banner() call fails
- Improved handling of empty available_scanners array (display '(None currently installed)')
- Added error checking to ensure functions are available before use
BEHAVIOR CHANGE:
- Menu now validates dependencies before displaying
- Better error messages if required functions are missing
- More robust handling of library sourcing failures
This should fix the issue where menu fails to display when libraries are not properly sourced.
