IRSA-7248: Fix combined Euclid spectra (and multi-trace chart) bugs

[jaladh-singhal]

Fixes IRSA-7248: refer to my comment on this ticket since it has evolved since it was created

• Allow re-render of useBasicOptions components when trace changes - this was a regression issue, likely introduced in this PR
• The chart modifications trigger addScatterChanges (to handle table source connections for other traces), which doesn't always have y defined causing chart to throw runtime error and get stuck loading

Testing

Firefly: https://fireflydev.ipac.caltech.edu/irsa-7248-combine-charts-bugs/firefly

• Upload a spectra file with more than one traces (use the Spitzer spectra linked in ticket)
• Open chart options (gears dialog), check you can change trace from "choose trace" listbox and it reflects changes in the listbox and trace options fields
• Do any modification. change chart title, apply -> change trace -> apply -> no errors in console/ chart shouldn't get stuck

Euclid: https://irsa-7248-combine-charts-bugs.irsakubedev.ipac.caltech.edu/applications/euclid

Combine a few spectra rows, and open chart options for the combined spectra chart. Then do same as above or items 3, 7, 8 from @lrebull's Euclid testing list. They shouldn't make chart freeze.

NOTE: multi-trace chart still has some problems when applying chart modifications from the dialog because some of them propogate to other traces and some don't and then changing trace causes things like error bars, redshift spectral frame to disapper, etc. But we should track them in separate ticket (since they may require some redesign of dialog itself).

very nice! i can't make it crash!

The code changes look good.
