Subject: [PATCH] fix: restore text paste in message editor (Quill)

The clipboard.onPaste override broke text pasting in Quill 2.x
where this internal API is no longer public. Replaced with a DOM
paste event listener on quill.root that only intercepts image
pastes and lets Quill handle text paste natively.
