fix(servicenow): give list-attachments limit a unique subBlock id

Read Records and List Attachments shared the subBlock id 'limit', so the
single-value-per-id store could bleed the value across operations. Rename
the new list-attachments field to attachmentLimit and map it back to the
tool's limit param.
