Fix dependabot auto-approve workflow GitHub Actions permission error

[Copilot]

The dependabot auto-approve workflow fails with GraphQL: GitHub Actions is not permitted to approve pull requests because the default GITHUB_TOKEN cannot approve PRs via gh pr review --approve.

Changes

• Replaced gh pr review --approve with hmarr/auto-approve-action@v4 - Uses GitHub API method compatible with default GITHUB_TOKEN
• Changed trigger from pull_request to pull_request_target - Required for Dependabot PRs to access workflow secrets
• Added contextual review messages - Include dependency names and update type

# Before
- run: gh pr review --approve "$PR_URL"
  env:
    GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}

# After  
- uses: hmarr/auto-approve-action@v4
  with:
    review-message: "Auto-approved ${{ steps.metadata.outputs.update-type }} update for ${{ steps.metadata.outputs.dependency-names }}"

Security boundary unchanged: workflow only runs for github.actor == 'dependabot[bot]' and doesn't execute PR code.

Original prompt

Auto-approving dependabot/fetch-metadata

Note

Ensures Dependabot PRs can be auto-approved and tweaks CI pre-commit behavior.

• Dependabot workflow: switched to pull_request_target and replaced gh pr review --approve with hmarr/auto-approve-action@v4, adding contextual review-message; still gated to github.actor == 'dependabot[bot]'
• CI: pre-commit now skips poetry-lock and poetry-check via SKIP env in ci.yml
