feat(metrics): add active users, actions queue/running to Prometheus (#42)

Extend the existing /metrics endpoint with 3 new application metrics:
- gitea_active_users_30d: users active in last 30 days
- gitea_actions_queue_length: pending action jobs
- gitea_actions_running_jobs: currently running jobs

No new dependencies — extends existing collector and statistic model.

Closes #42
