   Notification centre — interaction fixes.

   `.portal-notification-center` is `isolation: isolate`, so its children form
   their own stacking context. The backdrop inherited z-index 1130 from the
   rule it shares with the command palette (where the backdrop IS a top-level
   sibling), while the panel sits at z-index 1. Inside the isolated context
   that put the translucent backdrop *on top of* the panel, dimming it and
   swallowing every click — the panel rendered but could not be used.

   Scope both children to the centre and order them locally. The command
   palette's own backdrop is untouched and still needs its 1130.
