Implements comprehensive Docker monitoring with a dedicated agent that collects container metrics and reports them to the main Pulse server. Adds Docker-specific alert rules and threshold management with a redesigned UI. Backend changes: - Add Docker agent binary with container metrics collection - Implement Docker host and container models with CPU/memory tracking - Add Docker-specific alert types (offline, state, health) - Extend threshold system to support Docker resources - Add WebSocket message types for Docker agent communication - Implement Docker agent API endpoints for registration and metrics Frontend changes: - Add Docker monitoring page with host/container views - Add Docker agent settings panel for configuration - Reorganize thresholds page with Proxmox/Docker tabs - Add Docker-specific alert threshold management - Improve layout consistency with vertical stacking - Fix defensive null checks and TypeScript errors This change enables monitoring of Docker containers across multiple hosts with the same alerting and threshold capabilities as Proxmox resources.
