feat: add IPAM discovery from Proxmox with IP enrichment, improve workload insights, and enhance DataTable interactivity

Add /ipam/discover endpoint to automatically import IP addresses from Proxmox clusters with error tracking and audit logging, implement ensure_discovered_network helper to create "discovered-ipam" network for auto-discovered IPs, add import_discovered_ips function to parse IP interfaces and create subnet/address records with assignment tracking, enhance ProxmoxProvider.enrich_work
