Magfit popup window is too small and can't be resized.

I've been trying to use the Magfit tool in MavExplorer but the setting screen just doesn't fit in Ubuntu. I've used several different installs of Ubunutu (22.10 Desktop, and Budgie) on a couple of laptops and it's the same issue. I can't resize the window to access the run button.


It does work on the one windows install of MavExplorer I use.
Magfit_wmm.py works fine on all the machines tested.

Reproduce the Magfit settings window in MavExplorer on Ubuntu, using the reported screenshot and the known-good Magfit_wmm.py behavior as references. Locate the Magfit UI entry point, then verify that the full settings screen and Run button are accessible without relying on an unresizable window; check the behavior on Windows as well.
