Fix GUI bug when NetBox HTMX is disabled causing to render layout.html instead of just the desired element.

Example:

Initial state:

When HTMX is enabled globally on NetBox (works great)

When HTMX is disabled globally on NetBox, but my plugin stiil tries to use HTMX:

I can tell why this is happing, on this Status Badge used as example, it is extending NetBox base/layout.html template. Removing it solves the visual problem when HTMX is disabled globally, but then when it is enabled, the HTMX just does not work. I still didn't got the time to investigate why.

I would appreciate some help on solving this, mainly from one that deeply understands how NetBox use HTMX and why it relies on layout.html to work (at least on my case).
