How much hotter does a kettle of water get if the thermostat gets
stuck on and the water continues boiling? If it doesn't get any
hotter, where / how is that surplus energy being dissipated?

Didn't you pay any attention at all in your science lessons?
At normal atmospheric pressure water boils at 100 degrees - period.

That is almost true.
water boiling at normal pressure is at 100C is more likely to be correct.
Its quite possible to have water under normal pressure above 100c and
not be boiling as anyone that has been scalded when a glass of water
erupts while being removed from a microwave will be able to tell you.
Maybe they didn't cover that in your science lessons?
