Copies Playwright e2e tests (58 specs, 300+ tests) designed for cross-app
testing. Adapts API mocks to match real Aeroflot dictionary format (title
objects with multilingual keys), adds board/schedule/days endpoint mocks,
and provides Angular-specific Playwright config on port 4203.
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.
