Fix NET-TIMEOUT issues and improve QA check for false positives

lib/threat-intelligence.sh:
- Add --max-time 10 to AbuseIPDB API curl call (line 47)

tools/update-attack-signatures.sh:
- Add --timeout=60 to ET Open rules download wget (line 68)

tools/toolkit-qa-check.sh:
- Improve NET-TIMEOUT detection to exclude false positives:
  * Skip comment lines
  * Skip echo/string statements
  * Skip variable assignments with pipes
  * Only flag actual network calls without timeouts

This reduces false positive NET-TIMEOUT detections from 10 to 2.
