Parameter editor chart does not properly handle infinite values

See this:

https://policyengine.org/us/policy?focus=gov.irs.deductions.itemized.salt_and_real_estate.cap.JOINT&region=enhanced_us&timePeriod=2026&baseline=2&reform=56251

It's correctly specified as 10,000 from 2018 to 2025, inf otherwise: https://github.com/PolicyEngine/policyengine-us/blob/master/policyengine_us/parameters/gov/irs/deductions/itemized/salt_and_real_estate/cap.yaml

Should display a line in that range.

In terms of displaying, since we can't plot infinity on a chart, we could:

• Assign an arbitrary, extremely high value to be a stand-in for JS's Infinity (could be, say, MAX_SAFE_INTEGER)
• (If this is possible) Manually add a chart break at the top of the chart whenever infinity is present among the values and plot along our new arbitrary replacement

This would allow us to visualize without having to arbitrarily calculate some sort of stand-in that could be wrong, error-prone, or misleading.

Setting something to infinity, on the other hand, could be a bit more challenging.

Incredibly, react-plotly does not natively support axis breaks

How to display infinity in the years it's that value is a separate issue from what I reported here. For now I think not displaying it is fine.

[anth-volk]

Note that this is almost certainly driven by infinity itself not being displayed, hence impossible to draw a line to meet with a point at infinity

[MaxGhenis]

Yeah for now we can suggest including the last finite value in the year prior to infinity in the country package (PolicyEngine/policyengine-us#5252), but let's keep this open as it would be cleaner to do it in the front-end
