/**
 * useFilterDropdowns
 *
 * Owns the open/closed state of the three mutually-exclusive popover dropdowns
 * (operator, value, date-range) plus the click-outside effect that closes them
 * all. This is the single "which dropdown is open" concern; it exposes the
 * container ref the effect watches and the individual open flags/setters.
 *
 * Behaviour is identical to the previous inline implementation — same effect,
 * same dependency array, same setters.
