Update Dispute Counter
Save a draft counter’s evidence. This is a full replacement of the draft’s evidence_items, built for autosave — call it as the merchant edits. Only a counter still in the draft state can be saved; saving a submitted or withdrawn counter returns 400.
Pass the revision you last read. If the counter changed since then (e.g. another tab saved it), the request is rejected with 409 so you can reload rather than silently clobber the newer edit. Any attached file_ids must reference files you own, or the save is rejected with 422.
