fix: only skip appointment-attachment merge when automated claim already has files

skipAppointmentAttachmentMerge was blanket-set for any autoSubmit path
(chatbot, Claim with AI batch automation, insurance-status auto-check),
so screenshots/files attached directly on the appointment were silently
dropped from the MassHealth Selenium upload whenever a claim was
auto-submitted. Now the merge is only skipped if the automated flow
actually supplied its own files.
