Add automatic trimming for domain names and forward host fields

[vishnugt]

Adds automatic trimming to domain names and forward host fields to prevent leading/trailing spaces.

I spent an hour debugging why my forwarding wasn't working... twice. Turns out I had invisible spaces in my container names 🤦‍♂️

Now the fields automatically trim spaces when you add domains or click away from the forward host field.
