Allow SMTP configuration in the User Interface again

[Napsty]

What version of Invoice Ninja are you running? ie v4.5 / v5 v5

What environment are you running? ZIP

Have you searched existing issues/requests? Yes

Additional context Currently the SMTP / Sending Server configuration is only possibly when editing the .env file. In the v4 this could be configured in the UI:

In v5 these settings are gone. Making it difficult for non-tech-savvy people to change the SMTP settings (e.g. changed password).

Please consider getting this back into the UI in v5.

I second this, it'd be great to have this back. Once set, it doesn't often require changing but it's nice to have it in a GUI form.

Any update on this happening? I've been messing with the env file back and forth for what feels like ages, but there's no way to readily test if the settings are correct. Programs like Flectra use a "Test Connection" option after configuring your settings to verify them. Would be great for IN!
