Adds anonymous startup telemetry (Umami) for DevGuard API and DevGuard Scanner, plus environment configuration examples to control/disable it.

Changes:

• Introduce a new telemetry package to build and send Umami “instance start” events (with optional API DB stats).
• Hook telemetry into DevGuard API startup (fx.Lifecycle.OnStart) and DevGuard Scanner CLI startup (PersistentPreRunE).
• Document and template telemetry-related environment variables in .env.example and docker-compose-try-it.yaml.
