Add option to limit the width of the desktop notification bar

[panreyes]

Is your feature request related to a problem? Please describe.
The width of the notification bar is too long and uncomfortable for me.
I already implemented the feature in MeshAgent, I will soon implement the MeshCentral side of it.
Related to
Ylianst/MeshAgent#331
Ylianst/MeshAgent#323

Describe the solution you'd like

• Add an option to config.json: notifyDesktopBarMaxWidth
• In meshcore.js, use that value

try {
    require('notifybar-desktop').MaxWidth = notifyDesktopBarMaxWidth;
} catch (ex) {
    MeshServerLogEx(32, null, "notifybar-desktop MaxWidth not available (" + ws.httprequest.remoteaddr + ")", ws.httprequest);
}

I still have to find out how to:

• Add a configuration option to config.json
• Read it in the web server
• Send it to the agent

But I can confirm it's already working by hardcoding the width value.

Thanks for this feature, I'm also interested, the bar currently takes up too much space ^^

I would also like to know if it is possible to display the bar only on the main monitor and not on all monitors of the remote PC?
Let me explain: we use MeshCentral to connect and help stores with their cash registers, but the problem is that if I activate this bar, it appears on the cash register and the customer display. So if there is a customer at the cash register when the salesperson calls us, our name also appears to the customer, which is not ideal. I don't know if it is possible to correct this in the code so that it is only displayed on the main screen?

I'm sure it can be done, but it would also require changes in the agent, as the code for putting the notification bar in each monitor is embedded. Feel free to propose it here first: #7622 (comment)

After that it can be added to MeshCentral too
