Will Miao 3c83e78d9f feat(ui): auto-newline after pasting URL in download and batch-import textareas
Extract auto-newline-on-paste logic into shared setupAutoNewlineOnPaste() utility in uiHelpers.js.
Apply it to both the Download modal (modelUrl) and Batch Import modal (batchUrlInput)
textarea, so users can paste multiple URLs in succession without manually pressing Enter.
