* 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
* Editorconfig: Add space_before_self_closing setting
This was a difference between the way dotnet-format and Rider format code. See https://www.jetbrains.com/help/rider/EditorConfig_Index.html
* Editorconfig: Keep 4 spaces indentation for Swagger JSON files
They are all formatted that way, let's keep it like that.
* Apply dotnet-format, mostly white-space related changes
* Wallet import: Surface detailed error messages
Similar to #4205, this checks if the input is an output descriptor and display more detailed information about why an import might fail.
* Add test cases
Checks if the input is an output descriptor and explicitely handles that case instead of catching any errors. This allows us to display more detailed information about why an import might fail.
