Remove the per-route 'export const instant = false' opt-outs now that the root layout carries the single Cache Components opt-out. Child pages inherit the opt-out, so admin/mod/radio leaf pages that only access cached or DB data stay instant while runtime-dependent pages remain dynamic. Update the staff-smoke contract test to assert the root-layout contract.
.catch(() => null) unioned the query result with null, so destructuring
the first row failed typecheck (TS2488). Return an empty array on failure
instead and drop unused connection/desc imports.
