[Bug]: Validation needed on Connect New Device IP Address/Hostname

[fifieldt]

Hardware

Connection Type

HTTP

Local or Hosted

https://client.meshtastic.org

Firmware Version

2.6.0

Description

Steps to reproduce:

1. Open https://client.meshtastic.org/
2. New connection --> HTTP
3. In the 'IP Address/Hostname' box, paste in a string with characters illegal for an IP or hostname, like "http://127.0.0.1:4403/"

What should happen:

• Suitable error message should be displayed, connection is prevented

What happens instead

• Connection attempt goes through, and then fails cryptically since it's not a valid hostname/IP

Relevant console output

100% agree on this, we need do some plumbing fixes inside the @meshtastic/js repo to support this, but overall this is something we need to add, as I am consistently annoyed when I dont get a connection but can still see the UI
