Fix React hooks ordering error after blueprint submission

Moved useMemo calls for `summary` and `voxels` above the early `if (success) return` in SubmitForm. Placing hooks after a conditional return violated the Rules of Hooks (React error #300), causing a blank page after a successful PR submission.

Also filters BentoBox itself out of the ChipPicker in PresetEditor so it no longer appears as a selectable addon.
