Modern.js SSR intercepts all routes before any Express middleware,
so the API proxy runs as a separate Express server on port 8080.
Modern.js runs on 8081. The proxy uses curl subprocesses which go
through the system HTTPS proxy (GOST) with a proper TLS fingerprint
that the Aeroflot WAF accepts.
Usage: node scripts/dev-server.mjs (replaces pnpm dev for full-stack)
Also: remove stray e2e-angular test directory, fix env default to
same-origin /api.
