Backend looks good to me so far :)

@MichaelBuessemeyer I think you can already have a look at the frontend :)

Thanks a lot for all the effort to integrate SAM2. Works perfectly 🚀

During reviewing I only found minor suggestions and one confusion: One request param in the backend is annotated as "in target mag" and the frontend always seems to the bbox in mag 1.
But the feature still seems to work perfectly 🚀 -> Testing went well, I have no suggestions in that regard

Frontend & Backend LGTM 🚀

Didn't do another round of testing as there weren't much functional change. Just ping me in case I should restest :)
