Looks good!

We probably could have used the class level @RequestMapping like we do in ImageController.java:
https://github.com/R-Sandor/FindFirst/blob/6eeb31351850568c884f28225676dfdb542a4704/server/src/main/java/dev/findfirst/core/controller/ImageController.java#L16

but I wasn't consistent with that in the BookmarkController.java, where every path has the full path.

The RequestMapping on the class prefixes all mapping with the class level path.
I am only mentioning it here as a nice to know if you see that in the code that's what the class level Mapping is doing.

Very nice PR again! Thank you! 🚀
