perf(dashboard): trim blur radii (orbs 40->28px, header backdrop 28->18px)

Browse source 
GPU fill/blur cost scales with radius. The sidebar aura orbs already fade to
transparent at 70% of their gradient, so dropping their blur 40->28px shrinks the
composited bounding box with no perceptible softness loss. The frosted header's
backdrop-filter is re-blurred whenever the orbs drift behind it; 28->18px cuts
that per-frame work ~a third while keeping the frosted look. Relief is biggest on
weak GPUs (the machines people complain about).
