Add a dashboard for Splits

[leruaa]

As discussed on Discord, here is a first draft of a chart showing pool asset distribution, including splits.

I'm not sure if this should be integrated to the claim process or on a "Dashboard" page, wdyt?

I think this is great - thanks for taking the time to write code in the same style as the rest.

The vizualisation is really informative and useful, the only thing is it requires quite a bit of 'insider' knowledge about how the system works (e.g. without looking it up idk the difference between withdraw and distribute).

I'd be interested to get some design/ux feedback from other contributors on this as I think it would be nice to either have an "advanced" setting that would toggle this display, or to explain it a little more.

I think with either of the above we could also build in the functionality to interact with the splits contract.
