fix(16): resolve 3 UAT issues — update flow, batch cancel, text commands

- Fix update sub-workflow: remove unsupported GraphQL filter arg, fix node
  reference (Format Pull Error → Format Update Error), fix field case
  (data.image → data.Image)
- Fix batch cancel: connect Route Callback output 20 (batchcancel) to
  Prepare Batch UI Input (was empty connection array)
- Fix text commands: change .item.json to .first().json for paired item
  breakage after GraphQL chain expansion; convert Send Batch Confirmation
  from Telegram node to HTTP Request to fix double-serialized reply_markup
