Thanks for jumping into the design tool consistency efforts @akasunil 🙇

This PR tests as advertised for me and helps round out the Social Links design tools given the block already supports background color and padding.

✅ Social Links border is configurable via Global Styles
✅ Global Styles apply correctly in the editor and frontend
✅ Block instance borders take precedence over global styles
✅ Block instance borders display correctly in both the editor and frontend

Nice work! I'll get this merged and update the border tracking issue accordingly.

P.S. To help encourage others that may be less familiar with global styles and block supports, would you mind updating the PR description here, and the other open block support PRs, with more detailed test instructions? Ensuring the block support adoption works correctly is slightly more involved than the current instructions suggest, that's all.
