Stop per-request module re-imports leaking memory in production

Browse Source 
Page rendering imported the SSR bundle and .server.ts modules with a
unique ?t= query on every request, in production too. Each one became a
new, never-evicted module record (and re-ran module top-level code), so
RSS grew with request count. Cache-bust only in dev via importFresh.
