fix(test): Fix flaky customerDetails billing permissions test

The tooltip on disabled menu items in CompactSelect/MenuListItem has a
500ms delay before appearing. Under CI load, this delay plus React
render time can exceed findByText's default 1000ms timeout, causing
intermittent failures. Extend the timeout to 2000ms.
