chore(query-keys): drop insightsGeneralStatus leftover from W3f route removal

The `/api/insights/general-status` route was deleted as part of W3f
(commit edae569) when the general-status panel migrated into the
combined comprehensive insights payload. The matching query-key factory
+ its integrity test assertion were missed in that cleanup pass.

The test now pins `insightsBpStatus` instead — the locale-in-status-key
invariant remains covered.
