Add comprehensive integration tests for safe output job configurations

These tests verify that all safe output job types properly include required
environment variables like GH_AW_WORKFLOW_ID. Tests cover both individual job
builders and consolidated safe outputs job.

Tests found issue: Individual job builders (create_issue, create_discussion, etc.)
are missing GH_AW_WORKFLOW_ID environment variable, which is only added in
consolidated mode.
