feat: add manual trigger support for fuzzer fix automation

Add workflow_dispatch trigger to allow manually running the fix
automation on specific issues via:

  gh workflow run fuzzer-fix-automation.yml -f issue_number=5322

This is useful for:
- Testing the workflow before it's merged to develop
- Re-running analysis on existing issues
- Triggering on issues that were created before workflow was added
