Add toggleable system temperature monitoring widget

[SpectrixDev]

Added a toggleable system temperature monitoring

• Introduces a new, standalone temperature monitoring widget to the bar, displaying real-time CPU and GPU temperatures.
• Uses multiple providers (psutil, sysfs, nvidia-smi) for broad compatibility.
• Adds a "System Temps" toggle to the settings GUI under "Appearance > Modules" to control visibility (default: off).

There's probably room for improvement, maybe even if anyone has ideas of a better place to put it I'd be happy to change it. I've only tested it on an AMD only rig so I'd say it would need some extra testing potentially.

Thanks! I'll try it out when I have time.

Hi, sorry for the extreme delay. I'm testing it right now and works great!
When I have the time, I'll design the vertical layout for this.

I've updated the font and boldness etc. All the other commits were just keeping it up to date since I use my own fork of it so I can have the temps on my end
