notify on tls error

[ineeee]

currently a connection fails silently when connecting to a server with an invalid tls certificate. its possible to read the error in the config/halloy.log but its not user-friendly.

it would be an improvement to show an error in the window mentioning why it failed to connect.

environment: windows 10, halloy 23.1-alpha1, own irc server with self-signed cert.

Thanks, I'll look into that.
If you want to accept a invalid cert you can use: dangerously_accept_invalid_certs: true
