🌟 Convert Attribute Connections to Pills with Expandable Hover + Remove Option

We're updating the design of connected attributes to match the “Display on Step” pill style. This includes:

• Displaying attributes as pills with logos

• Supporting expand-on-hover to show full name (including second line)

• Adding an “X” to remove an attribute directly from the step

This will create a cleaner, more consistent UI and improve manageability for steps with multiple attributes.
