fix: pin dependabot-automerge reusable workflow to SHA

[don-petry]

Summary

• Pins dependabot-automerge-reusable.yml@v1 → @ee22b427cbce9ecadcf2b436acb57c3adf0cb63d # v1 to satisfy the Action Pinning Policy
• SHA was looked up via gh api repos/petry-projects/.github/git/refs/tags/v1 — the v1 tag was updated since the prior fix attempt (PR fix(ci): pin dependabot-automerge reusable workflow to SHA #102), which is why that fix no longer satisfied the compliance audit

Closes #87

@don-petry — this is the code owner for .github/. The change pins dependabot-automerge-reusable.yml@v1 to its current SHA (ee22b427) to resolve the compliance audit finding in issue #87. The v1 tag was updated since the prior fix attempt (PR #102), which is why that fix no longer satisfied the audit. Please review and merge when ready.

Summary

This PR pins a reusable GitHub Actions workflow call from a mutable @v1 tag to an immutable commit SHA (ee22b427), resolving compliance finding #87. All CI checks pass (CodeQL, SonarQube, CodeRabbit), the change is a single line, and it is a net security improvement with no regressions introduced.

Findings

Info

• [info] .github/workflows/dependabot-automerge.yml:39 — Pre-existing 'secrets: inherit' passes all caller secrets to the reusable workflow. This is not introduced by this PR but is worth reviewing separately — callers should pass only the minimum required secrets.
• [info] .github/workflows/dependabot-automerge.yml:39 — SHA ee22b427cbce9ecadcf2b436acb57c3adf0cb63d cannot be independently verified in this review context, but the PR author (org MEMBER) attests it was retrieved via 'gh api repos/petry-projects/.github/git/refs/tags/v1' and SonarQube/CodeQL scans passed with no findings.

CI status

All CI checks passed (CodeQL, SonarQube, CodeRabbit) with no findings.
