[Enhancement] Add option to scan your own device for open ports

[ghost]

Even though we can see our own IP on the top of the screen, we can't tap somewhere and scan for open ports on the same device.

Though you're supposed to know what ports you already have open, it would be great from security integrity prospective to allow us scan the device.

I currently use another device to scan my own device, and it would be better to maybe show our own host in the list when running discovery with a tag of "Current Host" and allow port scanning.
