Chmod changed on processed files

Description

When processing a file the resulting file has different permission flags the original. Maybe behaviour is exepected, but I couldn't find an issue or a plugin to tackle this.

Steps to Reproduce

Add a file to process to the library with full permissions (777).
Wait for Unmanic to process the file.
Check the resulting file permissions.

Expected behavior: the processed file keeps the original file's permissions.

Actual behaviour: the processed file has different permissions (644), safer, yet different.

Reproduces how often: 100%
