Pull Request Overview

This PR converts the defaultMaps object from a static object to a computed property to ensure reactivity when globalConfig changes. This allows the component to properly react to dynamic configuration updates.

• Wrapped defaultMaps in a computed() function to make it reactive to globalConfig.value changes
• Added explicit ComputedRef type annotation for better type safety
• Updated the reference to defaultMaps to access its .value property
