Subject: [PATCH] fix: use execute_query_single for duplicate checksum check
 v2.2.17

Fixes 'list indices must be integers or slices, not str' error when
uploading a duplicate file. execute_query returns a list, so accessing
existing_file['file_id'] caused TypeError. Now uses execute_query_single
which returns a single dict row.
