feat: Add image preview and remove action in block editor

[jojo58fr]

Description

Adds image preview support in the block editor sidebar after upload, along with a dedicated Remove image action.

This change improves the image upload UX for MEDIA and LINK blocks by:

• showing an inline preview of the selected image
• allowing users to remove the uploaded image explicitly
• matching the Remove image button size/style with the existing Remove Block action
• resetting the file input so the same file can be re-uploaded without friction
