[Nodesignal bounty] Admin UI

[callebtc]

This generous bounty by Nodesignal Podcast of 300,000 sats is for creating an Admin UI for Nutshell

Nutshell mint should have a simple admin UI that can only be accessed by the admin of the mint. The admin UI should allow the admin to 1) change settings of the mint and apply them 2) observe activity of the mint, and 3) offer basic monitoring properties of the mint (number of entries in the database, number of requests in recent past) and the underlying os (free disk space, used CPU by nutshell) etc and 4) allow admin-level actions like triggering a key rotation, or issuing ecash without requiring a payment.

You can be creative in the implementation of this admin UI, as long as it is useful to a mint operator. The admin UI can run as a separate daemon (with a local web server). Communication with the nutshell mint should be over an API.
