The four inline (non-DS::Tooltip) tooltips had drifted: three used
p-2 rounded w-64, one used p-3 rounded w-72 with shadow-lg, and all used
rounded (4px) where DS::Tooltip uses rounded-md (6px). Unify them on
p-2 rounded-md w-64 — radius now matches DS::Tooltip and the lone
p-3/w-72/shadow-lg outlier is gone, so the dark tooltips read
consistently.
