fix(export): resolve edits into the original row; mark media rows

m.replace events no longer appear as their own "* text" line — the original row gets m.new_content and an (edited) marker. Media rows carry a [Image]/[Video]/[Audio]/[File] prefix and the JSON export includes mediaUrl; the UI notes attachments aren't included. Unit-tested.
