Add cancel/back options to all user input prompts

Changes:
- Added "0) Cancel" option to all menu prompts
- Added "(or 0 to cancel)" to all text input prompts
- Ensures users can back out of any operation at any time
- Scripts affected:
  - website-error-analyzer.sh (scope selection, time range)
  - 500-error-tracker.sh (time range selection)
  - wordpress-cron-manager.sh (all domain/user input prompts, status checks)

User Experience Improvements:
- No more being trapped in prompts
- Clear cancel instructions on every input
- Consistent "Operation cancelled" messaging
- Proper exit codes (0 for user cancellation)

Tested:
✓ website-error-analyzer.sh - cancel on scope selection
✓ 500-error-tracker.sh - cancel on time selection
✓ wordpress-cron-manager.sh - cancel on domain/user input
✓ All cancellations return cleanly to menu
