Clean up notes array formatting from the live add/delete round-trip test

The Input Interface backend's note-insertion left a stray comma-on-its-own-
line and merged the closing bracket onto the last item -- syntactically
valid but inconsistent with the rest of the file's formatting. Fixed
whitespace only, no content change. Confirms their real (non-mocked)
end-to-end test: submit-task -> delete-task round trip against the live
backend, back to 17 total subtasks with unique ids, the deleted subtask's
audit-trail note correctly retained per their by-design behavior.
