feat(deployments): docker tabanlı proje yönetim ve otomatik deploy sistemi ekle

Docker Compose projeleri için tam kapsamlı yönetim paneli ve otomatik deployment altyapısı eklendi.

Sistem özellikleri:
- Belirtilen root dizin altındaki docker-compose dosyası içeren projeleri tarama
- Git repo bağlantısı ile branch yönetimi ve klonlama/pull işlemleri
- Docker compose up/down komutları ile otomatik deploy
- Gitea webhook entegrasyonu ile commit bazlı tetikleme
- Deploy geçmişi, log kayıtları ve durum takibi (running/success/failed)
- Deploy metrikleri ve dashboard görselleştirmesi
- Webhook token ve secret yönetimi ile güvenlik
- Proje favicon servisi

Teknik değişiklikler:
- Backend: deploymentProject, deploymentRun ve settings modelleri eklendi
- Backend: deploymentService ile git ve docker işlemleri otomatize edildi
- Backend: webhook doğrulaması için signature kontrolü eklendi
- Docker: docker-cli ve docker-compose bağımlılıkları eklendi
- Frontend: deployments ve settings sayfaları eklendi
- Frontend: dashboard'a deploy metrikleri ve aktivite akışı eklendi
- API: /api/deployments ve /api/settings yolları eklendi
