🐛 Balance the padding of the desktop dropdown menu (#3058)

The submenu panel carried both `pt-2` and `p-5`. Tailwind emits shorthand
utilities before their longhand counterparts, so `padding-top` resolved to
`0.5rem` while the other three sides stayed at `1.25rem`, regardless of the
order the classes appear in the markup. The first submenu entry sat flush
against the top edge.

This went unnoticed while the panel was translucent. v3 made it opaque, which
draws the edge and exposes the imbalance.

Drop `pt-2` so the panel keeps the uniform `p-5` it was styled for. No new
utility classes, so the compiled stylesheet is unchanged.
