feat: REST API (gorilla/mux + slog) + trigger controller + main.go wiring

- controllers/trigger_controller.go: полная реализация, HTTP->Ingress+Service, Cron->CronJob - internal/config: добавлены IngressHost, APIToken - internal/api/router.go: gorilla/mux роутер /v1/namespaces/{ns}/... - internal/api/handler/: functions, triggers, invocations, base handler с slog - internal/api/middleware/: auth (Bearer token) + logging (slog) - main.go: запуск operator + HTTP сервера параллельно - go.sum: добавлен gorilla/mux v1.8.1
