feat(dağıtım): Docker imajı ve Axum'un arayüzü sunması

- Çok aşamalı Dockerfile: Node (arayüz) → Rust (release) → debian-slim, root olmayan kullanıcı
- Axum, STATIC_DIR tanımlıysa derlenmiş arayüzü sunar (SPA yönlendirmesi)
- Önbellek başlıkları (HTML no-cache, /assets 1 yıl), gzip/brotli sıkıştırma, istek logları
- Bilinmeyen /api/... → JSON 404; SIGTERM'de düzgün kapanış
- HEALTHCHECK (/api/health), .dockerignore, docs/DEPLOY.md
