Display currency parameters

The parameter view (here Cesium v1 for reference), will be useful in dev mode and for people to understand better Duniter-v2.

This will only interact with Duniter RPC api in its simplest form (key / value requests). Example is available in Ğcli: https://git.duniter.org/clients/rust/gcli-v2s/-/blob/4e1da26b3db40f61b14ef05bd716f4ba98e5f3f2/src/commands/runtime.rs

This currently gives this result:
