Fix ActiveAdmin icons with Font Awesome 7

Description:

After bumping @fortawesome/fontawesome-free to 7.x, icons in the ActiveAdmin UI render as empty squares. The issue is arctic_admin's _icons.scss still defaults $font-icon to 'Font Awesome 6 Free', 'Font Awesome 6 Pro'. With Font Awesome 7 installed, the @font-face registers "Font Awesome 7 Free", so arctic_admin's font: declarations fall back to a font the browser doesn't have.

Fix:

In app/assets/stylesheets/active_admin.scss:

• Replace the FA @imports with @use … with ($font-path: ".") so the override actually propagates through FA7's module system.
• Keep the $font-icon: 'Font Awesome 7 Free'; top-level override for arctic_admin, which still uses @import internally and picks up !default overrides the old way.
