fix(skills): keep skill title input transparent in dark mode (#2710)

The skill name Input on the detail editor uses `bg-transparent px-0`
to render as flush, chrome-less text. The base Input component also
applies `dark:bg-input/30`, which Tailwind keeps because it lives in
the `dark:` variant. In dark mode this exposes a 30% white fill that
appears flush against the text — looking like missing left padding.

Add `dark:bg-transparent` to the className so the override wins in
both color modes.
