[BUG] Spectrum-at-spaxel tool raises JSON warnings in uncertainy viewer

Description

I was doing some testing with the updated MaNGA cube (https://stsci.box.com/shared/static/gts87zqt5265msuwi4w5u003b6typ6h0.gz) and noticed that when using the spectrum-at-spaxel tool in the uncertainty viewer, every mouse move resulted in a warning:

/Users/rosteen/opt/anaconda3/envs/viz_dev/lib/python3.12/site-packages/jupyter_client/session.py:721: UserWarning: Message serialization failed with:
Out of range float values are not JSON compliant: inf
Supporting this message is deprecated in jupyter-client 7, please make sure your message is JSON-compliant
  content = self.pack(content)

We should figure out how to handle this case better - there are infs in the uncertainty because we convert a 0 inverse variance to inf stddev, but it's all in masked locations.

How to Reproduce

Load linked file in Cubeviz, use the tool.

That's to add to a table, the bug mentioned above is for mouseover which shouldn't go through table.... but we likely need a generalized solution that works for both since the same issue would likely occur if using the markers plugin.
