refactor: migrate server provisioning to Cloud Orchestrator service

- Remove Queue-based server provisioning (moved to cloud-orchestrator)
- Add manage_server tool with Service Binding to Cloud Orchestrator
- Add CDN cache hit rate estimation based on tech_stack
- Always display bandwidth info (show "포함 범위 내" when no overage)
- Add language auto-detection (ko, ja, zh, en)
- Update system prompt to always call tools fresh
- Add Server System documentation to CLAUDE.md
