Cover unnamed-fallback branches of attachment remove descriptions

Add three Paparazzi snapshot tests rendering each composer attachment
item (image, video, file) with a copy of the existing preview data that
clears the title and name, exercising the previously uncovered fallback
arms of fileAttachmentRemoveDescription and mediaAttachmentRemoveDescription.
Extract a shared MessageComposerAttachmentItem helper to dedupe the
preview-handler wiring across the four media-item previews.
