Calculate router liquidity + utilization over time

[rhlsthrm]

Background

We need to calculate router utilization so we can see if routers or AMM liquidity is the bottleneck.

Linked Issues & Documentation

This should be easy to get an idea of based on onchain metrics. Basically, just need to sum up value of all transfers that are in the Executed state at any time and then divide that by router liquidity for a given chain if you plot a time series of this^ we would get a % over time of router liquidity that's being used

Definition Of Done

Router liquidity is measured.

Tasks

• [ ] Need some more discussion around how to show this info.
