FR: Allow Device name and Web UI to be different

[hakan42]

I am using Tailscale as my VPN solution. I can expose the Web UI of Tasmoadmin and access this via Tailscale, but if I want to work with the specific devices (e.g. one of the switches) , the machine name is being used to generate the Web UI.

I cannot set the device name to the tailscale name either because Tasmota itself has no way of running the tailscale client on a simple switch or LED controller.

What should we implement

Add another field to devices.csv, e.g. instead of:

3,"A1T MetarMap",a1t-metarmap-5791.mydomain,foo,,bulb_1,3

have an additional field:

3,"A1T MetarMap",a1t-metarmap-5791.mydomain,a1t-metarmap-5791.mytailscale-domain,foo,,bulb_1,3

The first name would be used for TasmoAdmin to talk to the device (as it is now), and the second one to generate the "Web UI" link.

FTR - this seems not to be the same issue as #257
