fix(rows): open on the first tap on iPhone, and round the hover highlight

On a touch screen a :hover on the tap target makes iOS spend the first tap
applying the hover and only open on the second — the double-tap Kristian hit
on tasks (and notes). The row hover is gated behind @media (hover: hover)
now, so a touch has no hover to apply and the first tap opens. The note
row's action buttons, which the hover used to reveal, are shown outright on
touch instead. And the task-row hover highlight is a rounded box (border
radius on the row), the same corner as a note in the list.
