make governance more visible

[brenzi]

Currently, Encointer governance by council is entirely transparent, but barely visible.

While we use the collective pallet, we do not use democracy, which leads to standard frontend misinterpretation of what we can do.

Therefore, js/apps shows no motions under "governance". neither does subscan.

So, one has to query collective.voting storage in order to follow council activity. This should be imporved if we want our communities to follow and understand governance.

I'm not sure if it is worth using polkassembly or subsquare because they assume standard democracy V1 pallets and will eventually support gov2. But they most certainly won't support encointer's subsidiary democracy

So we may need to offer our own frontend in the first place. maybe integrated into explorer?
