CRITICAL FIX: Handle background job failures in wait command

Line 1900: Changed 'wait' to 'wait || true'
- Background IP reputation update jobs may fail (incomplete features)
- With set -e, failed wait command exits entire script
- Using '|| true' allows script to continue even if background jobs fail
- Allows threat score calculation to complete and next functions to run

This fixes the script exit issue after 'Calculating threat scores...'
