fix(gtk): adjust background CSS class dynamically on config reload

Browse Source 
Currently the `background` CSS class is added once on startup and never removed
or re-added. This is problematic as that if Ghostty was started with an opaque
window but then its config was reloaded with a `background-opacity` less than 1,
the window won't actually become translucent, and it would only appear as if the
background colors had become faded (because the window is still styled to be
opaque).
