fix(web): Duplicate Side-by-Side path highlighting fix

[qtemp]

Description

• On the duplicates side-by-side view, changed to only highlight the File path (second informational line) when the displayed values are different.
• Changed the tooltip for the File path to show "File path" instead of "Full path: " + originalPath.
• Changed the tooltip for the File name (1st row) to show "Full path:" + originalPath.

This helps identifying quickly whether the duplicate image is in the same folder or a different folder.

How Has This Been Tested?

• Create a duplicate image in a different folder, can be same name or different. Verified paths are highlighted.
• Create a duplicate image in the same folder but with a different name. Verified paths are not highlighted.
