* Pluginify on chain wallet setup
This PR fixes a few logical points in the wallet setup flow to allow more extensive plugin flexibility; It also fixes an issue when building plugins that requires an Altcoin config profile. Here is an example showcasing the Liquid+ plugin using this to enforce that it is a hot wallet (a requirement it has) and that import to RPC is always set, and a new option that is used to configure the wallet further https://i.imgur.com/pDPQ73v.gif
* Update BTCPayServer/Controllers/UIStoresController.Onchain.cs
* update nbx
* Add payjoin option to hot wallet setup
Enables payjoin by default when creating a hot wallet and offers the user an opt-out.
Test fix
* Display PayJoin option only if it is available
* Test fixes
* Update hot wallet checks
* Test fix after rebase
* Use toggle buttons for enabling options
