/**
* The Pause/Resume control, in the two places a pause is a valid answer to what
* the reader is looking at: the foot of the sidebar, where it belongs to the
* resolver rather than to any page, and beside the detail of a query that was
* blocked.
*
* It reads `Health.protection` rather than `/api/pause` so it cannot contradict
* the Diagnostics health strip, and it renders nothing at all while protection
* is unavailable or unknown — pausing a resolver that has no filter snapshot
* would change nothing an operator could observe, and a state health has not
* confirmed does not name an action either.
*
* A pause says so, wherever the control is. "Resume" alone names an action
* without stating the state it would end, and with the header indicator and the
* Overview status row both gone the sidebar is the only place most pages can
* carry that fact at all: a paused resolver would otherwise leave no trace
* outside the Diagnostics page. The line and the health strip cannot disagree —
* one `protection` reading, one clock format, and the expiry refetch in
* `useProtection` retires both at the same moment. An active resolver gets no
* line: the button says Pause, which is the whole message.
