feat: use device description as name on Dashboard for authenticated WS devices, if available

[KEGustafsson]

New implementation to add authenticated WS devices description as a name to Dashboard.
This fixes issues that #1705 had related for non-admin use cases.

Question for fine tuning of this PR is, should ws devices data be part of SERVERSTATISTICS or PROVIDERSTATUS feed?
Current implementation is adding it to SERVERSTATISTICS in deltastats.ts. It could be changed to index.ts and part of PROVIDERSTATUS.

This PR works for authenticated devices, right? So reflect that in the title and description.

Like for non-authenticated server you can send data to the server with echo '{"updates":[{"values":[{"path":"navigation.speedOverGround","value":3.15}]}]}' | wscat 'ws://localhost:3000/signalk/v1/stream?subscribe=none'but all you'll see on the list is ws.

Websocket devices, which are listed in Security/Devices/Devices list are the ones that are impacted. If device has description then that is used, fallback id.
If non-authenticated serves does not populated this list, then there is no change to current situation.

I haven't checked how things look with non-authenticated server, but need to check that too.

Use case is mainly SensESP and similar sensor devices, which are listed there and produce data to server.

I'll update title and description to address this feature in more precisely.

Title and description updated to highlight that PR target is to show authenticated WS devices from Security / Devices list.
