[Bug] Drag-and-drop images render twice in prompt — inline and as attachments

Bug Description
When dragging and dropping images into he chat input, they appear in two places:

1. Inline in the prompt text as [Image #1] [Image #2]
2. Above the prompt as separate attachment references

(└ [Image 1], └ [Image 2])

Previously, images only appeared in one location (as
attachments above the input). Now they're duplicated
in both spots.
