[REQUEST] For UTR units, display the unit's name rather than unit's qname in Fact properties

[strr]

What should we change and why?

At the moment, for any unit other than a currency, it is displayed in QName form.

Please consider using the metadata from the UTR so that instead of displaying a fact value as
Fact Value: 15,000 utr:MWh

They are instead formatted as something like:
Fact Value: 15,000 Megawatt-Hour (i.e. lookup the unitId in the UTR and output the unitName in its place)

Would it not be more appropriate to use the unit symbol here, rather than the name?

Perhaps we could put the name in a mouseover.

The UTR would also give us symbols for all the other currencies, but I think there are some subtleties around whether the symbol is normally before or after the value.

Symbol rather than name is fine with me.

These are some work-in-progress branches I just rebased from a while back. They make a number of related changes, including rendering a symbol when available. It also includes a tooltip for units on hover, and opens a unit legend window on click (although the rendering there is incomplete). I likely won't be able to prioritize work on this so feel free to use directly or simply as a suggestion.

@aaroncameron-wk - thanks that's really helpful! It solves I hit with getting an incomplete UTR map for complex entries.

I'll try to merge your UI changes with mine, as I was just using title attributes for the tooltip.
