[WIP] feat: display recently closed channels

[rolznz]

Partially addresses #114

• pass a query param to include closed channels so it doesn't break other parts of the app which expect only open channels
• Use pending_balances_from_channel_closures to get the local channel balance for the closed channel
  • research how to get the local balance in LND - maybe the event is sufficient
• Consume Close Channel Events to get the reason for the closure and so we only show "closing" state for force closures

There is currently a big downside: we do not know how much local balance the channel has at time of closing.

And we do not check if the funding transaction funds have moved, so we also cannot show the balance of the closed channel as pending balance on the savings balance card.

For channels older than 2 weeks, these are currently not shown.

Closing to look at alternatives - if LDK can return closed channels then this is not needed, and if they can return the peer alias then we also don't need to keep extra data on our channels.
