fix: update scale ID check in download_scale_results endpoint

- Changed the scale ID check in the download_scale_results function from "database" to "psychoscales.db" for improved clarity and accuracy in file retrieval.
- This adjustment ensures the correct database file is accessed when downloading scale results.
