[api] file name/path and size in archive metadata

[Guerra24]

Title. I have been requested this information for the deduper three times, see:

Guerra24/LRReader#21 (comment)
Guerra24/LRReader#33
Guerra24/LRReader#41

So I'm opening this for consideration 👀

All three of those are available and I don't mind adding file name and size -- I don't think path is a good idea as the archive objects are present in public API endpoints and you don't really want to expose server filesystem information there.

[Guerra24]

Could file path be restricted behind a toggle in the server to enable/disable it? Or that would be too much of a hustle just for this? This for users who only use it in a private network and don't mind it being "public".

So when disabled it will show only the file name and when using an API key/passwordless with it enabled it will show the entire path.

Looking at the dedupe tickets in detail I think the filename should be enough information for now. Not sure it'd be worth it to expose the path, sorry!

7256656 should have you sorted for the other two.
