Proposed Changes

I propose adding a GitHub Actions workflow to automatically approve and merge Dependabot PRs based on update type and dependency type:

• Auto-merge patch updates for all dependencies (production + dev)
• Auto-merge minor updates for development dependencies only

We could increase the levels (e.g., change patch to minor for all dependencies, and minor to major for dev dependecies if this flow works as expected.

Testing Instructions

We can test it after merging.

Pre-merge Checklist

• Have you checked for TypeScript, React or other console errors?

Thanks @wojtekn for improving this workflow! My main concern with this change was that the E2E tests pass before merging, and I see this is correctly configured:

The --auto flag enables GitHub’s auto-merge, which means GitHub will not merge immediately. Instead, it queues the PR and will only merge it once:

1. All required status checks pass (CI, linting, tests, etc.)
2. All required reviews are satisfied

so I think these changes can land and rely (and improve if necessary) on the current e2e tests.
