feat: universal LLM gateway with embedded multilingual admin console

- OpenAI-compatible gateway with intelligent routing via cortiq-router (allaigate) - Embedded build-free admin SPA at /admin: 7 languages (en/ru/de/fr/es/zh/tr), light/dark themes, hot config reload (no restart) - Admin API, per-request statistics + Prometheus /metrics, secret store, playground - English documentation (primary) with Russian translations (*.ru.md) Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

+//! Embedded static assets for the admin panel (SPA). The `web/` directory is compiled
+//! into the binary via `rust-embed`, so the gateway remains a single self-contained file.
+//!
+//! Served as the main router's fallback: everything under `/admin/*` not matched by
+//! an explicit route is served as a file; an unknown path under `/admin` falls back to
+//! `index.html` (the client-side hash router handles navigation).
