fix(e2e): handle bool parameter hydration race in fillParameters

The bool case in fillParameters blindly toggled the switch with a
single click. If dynamic parameters hydrated after the click and
reset the switch state, the final value was wrong, causing the
'overwrite default parameters' test to flake.

Mirror the retry pattern already used for string/number parameters:
read the current aria-checked state, click only if it differs from
the desired value, then verify and retry up to 3 times.
