On some environments, the file storing the next scheduled run timestamp for data analytics collection was written but left empty. This caused the analytics collection schedule to not persist correctly.

The root cause was a file written through a temporary file that was moved before it was fully closed and flushed. The fix uses the standard save_text_to_file utility, which ensures the content is correctly written before the final file is put in place.
