test: pin scoped import-map resolution for dynamic import()

The host names a dynamic import's referrer by script origin - a file:// URL - while scope keys prefix-match the referrer's canonical registry key. The origin must land on that key space or scoped lookups silently fall through to top-level imports, which is exactly what happened on iOS for local referrers. Android's derivation is correct by construction (the origin routes through CanonicalizeRegistryKey's file:// branch), but nothing pinned it; now a fixture inside a scoped directory resolves a bare specifier through import() and the spec asserts the scope's target wins.
