Code Review

This pull request refactors buttons in the dashboard widgets by replacing the btn-circle class with btn-icon, resulting in square-shaped icon buttons instead of circular ones. The changes are consistent and align with the stated goal. I've identified one potential issue where a padding utility class conflicts with the intended styling of an icon button, which may cause rendering problems. My feedback includes a suggestion to resolve this.
