test: prime only the EN catalog in the unit setup

The setup file runs once per test file and imported all eight message
catalogs, several hundred kilobytes each, which made setup the largest
share of a component-suite run. It now primes EN, the fallback floor of
the t() chain. A test that renders another locale primes it at module
scope through primeLocales(), which loads the catalog via the production
loader in a file-level beforeAll.
