fix: components cannot be drag/dropped

[mohasarc]

Description

This PR fixes the issue with components cannot be drag/dropped, and along the way does the following:

• [x] Refactor overlays
• [x] Show overlays for non-concrete elements (elements that don't have corresponding html like components and fragments)
• [ ] hover and select the component instead of its children.
• [ ] handle circular referance cases when drag/dropping components
• [ ] fix the issue with component children not having unique data-element-ids which cause overlays to overlap.
