refactor(app): rename the port field into address and support change the address and the port

[0x61nas]

Sorry for the late PR, I had to take some time to parse the project structure tree.

Current behavior

The Share a service window only allows the user to define the service port and the address it always defaults to 127.0.0.1

Proposed changes

• Replace the Port field name to Address
• We should support the formats Host:Port, IP:Port and Port (defaulting to 127.0.0.1)
• Adapt the app backend to parse the address correctly.

• Closes: In the Share a service window, the Port should be renamed to Address and support such format #5685

I don't know why the commits are un-signed. I suppose that I've messed up my gitconfig. anyway, I will fix that and open a new PR.
