Cannot connect to Tusc network

[grctest]

Describe the bug

Connecting to a Tusc node fails & subsequently the balances don't load on the main page.

I get the following error:

C:\Users\username\AppData\Local\Programs\Beet Blockchain Companion\resources\app.asar\node_modules\bitsharesjs-ws\lib\ApiInstances.js:2 wss://api.cryptotusc.com Failed to initialize with error Cannot read properties of null (reading 'call')

I believe that we need to use the tuscjs and tuscjs-ws libraries to interact with tusc nodes, not simply extend the Bitshares blockchain factory class.

To Reproduce Steps to reproduce the behavior:

Launch Beet, add a tusc account to your beet wallet, switch active account to the tusc account.

Expected behavior

A network connection to the TUSC nodes is established and Tusc balances are shown.

Desktop (please complete the following information):

• OS: Windows
• Version: main & develop branches

Additional context

Added more TUSC nodes, however this issue persists.

Edit: I was however able to successfully broadcast a raw-deeplink create_ticket operation, so perhaps we can just overwrite the inherited Bitshares class functions which are causing issue.

Edit: Also unable to upload a local airdrop (multiple transfers in one), because it queries the network for human readable prompt details (like usernames, asset symbols). It currently loops infinitely trying to connect.. hmm
