A botched sed command stripped the first import line from every admin
route file, breaking NextRequest/NextResponse references. Restored all
imports and added export const dynamic = 'force-dynamic' to all admin
GET handlers so Next.js 14 never serves a stale cached response after
a save — this was the root cause of changes appearing not to save.
