fix(sentinelone): count-agents can be asked about the whole fleet again

Declared as a boolean, isActive rendered as a checkbox in the toolbox,
and a checkbox has no empty state: the count was forced to one half of
the fleet or the other, with no way to ask for both. As text, an empty
field means the filter is not sent.

true/yes/1 and false/no/0 are read in any case, a real JSON boolean from
a playbook still works, and anything else is refused rather than folded
into false — that would answer a different question than the one asked.
