/**
 * BOOTSTRAP / F6 — boots the unified production bootstrap (buildApp) and asserts
 * the whole shell is intact on the single NestJS instance now that Express is gone:
 * the global security pipeline (helmet/CSP), the /uploads platform routes, the
 * migrated /api domains (with the JWT guard), the /api/health + /api/addons
 * platform/inline endpoints, and (in production) HSTS. This is the test that proves
 * server/src/bootstrap.ts + index.ts serve everything correctly without the legacy app.
