The function getFileNamesForDisplay() in classes/utils/GUI.class.php uses $transfer->downloads (an array) where an integer value is expected.

Problem: When viewing the transfers table on FileSender 3.3, PHP throws:

PHP Warning: Array to string conversion in classes/utils/GUI.class.php on line 484

The file name column displays "Array" before the actual filename.
Comparison:

• Line 479 (Incorrect): $dlcount = $transfer->downloads; (downloads is an array)
• Should be: $dlcount = $transfer->download_count; (download_count is an integer)
  Steps to reproduce:

1. Upload a file using FileSender 3.3
2. Navigate to "My Transfers"
3. Observe the file names column in the transfers table
4. Check PHP error logs
   Suggested Fix: Change $transfer->downloads to $transfer->download_count on line 479.
