* Decide whether the paginated sessions list should be silently
* re-fetched after an overview poll.
*
* The dashboard's FastAPI server and a terminal CLI are separate
* processes that share the same SQLite session DB. There is no
* inter-process push channel, so the Sessions page polls the 50 newest
* sessions every few seconds (the "overview" poll). When that poll
* surfaces a session id at the head of the list that we have not seen
* before, a new session was created in another process and the
* paginated list is stale — refresh it.
*
* Returns false on the very first poll (no baseline yet) and when
* either id is null (empty DB / transient empty response), so we never
* trigger a spurious reload on mount or while the DB is empty.
