pm: fix audit CI failures (real drift + missing label)

[hanwencheng]

Summary

Fixes two CI failures from the first pm-workflow-audit.yml run on main (after #127 merged):

1. Real drift detected: Auto-archive items workflow is enabled on the project, but expected-workflows.json marked it should_be_enabled=false. The operator turned it on via the UI (the recommended state per the original note). Flip the expected state to true so audit reports 11/11 match.
2. Issue-creation step crashed: could not add label: 'kind/automation' not found. The repo has 7 kind/* labels in pm/labels.json but no kind/automation. Switch the drift-issue creation step to kind/devx (which exists and fits — automation tooling = dev experience).

Note on commit count

The "Commits" tab will show 7 commits but only 1 is new (eaffdf5). The other 6 are the same commits that #127 squash-merged onto main. GitHub's file-level diff is the source of truth — only 2 files changed.

Test plan

• After merge, the daily cron at 14:00 UTC should report ok check-workflows: 11 matched, 0 mismatches and skip the issue-create step entirely
• Optional: gh workflow run pm-workflow-audit.yml --repo litentry/agentKeys to verify immediately
• If drift is ever detected in the future, the issue-create step will now succeed with kind/devx,priority/p2 labels
