Added a new 'danger' button variant to the button component for
destructive actions like deleting equipment or sites.
Changes:
- Added 'danger' variant to button component (red background/hover)
- Updated equipment delete button to use variant="danger"
- Updated site delete button to use variant="danger"
- Removed custom red color classes in favor of standardized variant
This provides consistent styling for all delete/destructive actions
across the application while maintaining proper button base styles
(padding, rounded corners, shadow, focus ring, etc).
