add color backgrounds for circuit type

NetBox version

v4.0.8

Feature type

Change to existing functionality

Proposed functionality

resubmitting this as a FR. (original: #17135)
See: #12216. When circuit type colors were first added the 3rd screenshot shows the circuit type column having the text highlighted when viewing circuits. This never seemed to make it into the original feature, or perhaps was a regression at some point.

Example:

This FR would be to have circuit types be highlighted in the same way that rack roles are highlighted.

Use case

Would make circuit types easier to distinguish visually when viewing circuits.
Circuit types already have the ability to assign a color to them, this FR would be to adjust the circuits display to reference the assigned circuit type color for the 'type' column.

Database changes

none.

External dependencies

none.

I'd be happy to contribute this! Would you mind assigning the issue to me?

Sorry, this was mis-tagged. It needs a milestone as it would introduce a new field on the CircuitType model.

Disregard. Assigned to you @pheus, thanks!
