Add Hash Comparison for File Name Collisions during Move and Copy Operations

[dev-michael-schmidt]

When copying or moving files with the same name, a dialog currently appears with options to cancel, skip, duplicate, or replace the files (and Apply this action to all files). This dialog provides useful information like file name, type, size, and last modified date to help users decide between the two files.

I would like to propose a feature/enhancement to this dialog: an option to calculate and compare file hashes (e.g., SHA-1) directly within the interface. This would give users an additional way to verify whether the files are identical beyond the visible metadata.

• Add a button to generate a hash for each file, allowing users to compare them before making a decision.
• The hash comparison could appear below or next to the existing details (file name, size, last modified).
• To avoid unnecessary I/O, make the hash calculation optional, allowing users to generate it on demand for one or both files as needed.

This would give users more confidence in their decision-making process when managing files with potential name conflicts.
