Display icon_default from Paragraphs Module in Frontend Editing Overlay

Problem/Motivation

The frontend_editing module does not display the icon_default (which is provided by the Paragraphs module) when adding Paragraph entities via the overlay. The proposed changes ensure that, when available, the icon_default is displayed in the overlay along with improved styling for a more cohesive experience.

Steps to reproduce

1. Enable the frontend_editing module.
2. Create or use a content type that includes a Paragraph field.
3. Open the overlay for adding a new Paragraph entity.
4. Notice that the icon_default from the Paragraphs module is not displayed.

Proposed resolution

Update the rendering logic in the frontend_editing module so that it conditionally displays the icon_default (provided by the Paragraphs module) in the overlay when available. In addition, apply styling enhancements to ensure that the icon appears consistent and visually appealing.

Remaining tasks

• Conduct thorough testing across different environments and configurations.
• Verify that the changes do not cause any unintended side effects.
• Gather community feedback and adjust the implementation as necessary.

User interface changes

• The overlay for adding Paragraph entities will now display the icon_default if it is available.
• Enhanced styling has been applied to ensure the icon integrates smoothly with the overall frontend editing interface.

API changes

No API changes are introduced; the update solely affects the presentation layer of the frontend_editing module.

Data model changes

There are no changes to the underlying data model. This update is strictly limited to the rendering and styling aspects.
