What happened

In multiuser mode, several of the endpoints in invokeai/app/routers/boards.py fail to check that the current user has privileges to modify or delete the image board in question. These endpoints should use CurrentUserOrDefault and their underlying routines should ensure that the board is owned by the user (or that the request is being generated by the authenticated admin user).

What you expected to happen

These endpoints should respect the ownership of the boards when running in multiuser mode.

@copilot please work on this one again. The PR you created was against the incorrect branch. It should be done against feature/multiuser
