fix(web): show an image placeholder for image-only queued prompts

A prompt queued while the agent is busy can carry image attachments
with no text; the queue strip rendered its bare text — an empty string,
so the row was just a blank button next to a remove cross. Queue items
now expose {text, attachmentCount}: image-only prompts render an
'image ×N' placeholder with a small badge, and any item carrying
images disables the load-back-into-input edit action (the uploaded
files can't be restored to the composer; editing would silently drop
them — remove stays available). Verified with component render tests
for the three shapes (image-only / text-only / text+images).
