[FEAT] extra badges for non card view

Extension Badge

Shows the file format (JPG, NEF, HEIC, MOV, etc.).

• Position: configurable (top-left, top-right, bottom-left, bottom-right)
• Color: configurable per type (photo / raw / video)
• Can be hidden entirely

Duplicate Badge

Shows when a file has duplicates (same MD5 hash found elsewhere).

• Green 2× ORIG — this file is the original, 2 copies exist
• Red 2× DUP — this file is a copy of another file
• The number reflects total copies including the original

Interesting, but my concern is that it could clutter the viewport.
I'm not opposed to this idea if it's going to be optional, though.

Correct this is very personal - and for me this is a Nice to Have - and as always for this type of extras this should be optional / configurable....

And to make it more clear - a small screenshot from my own "running on my NAS solution" where you can see what I build myself and how you can configure this and how it reflect in my "thumbnail" view

(Sorry it is in Dutch but I'm sure you can understand it...)
