feat: IPAM improvements - server/node subnet binding, theme color fixes

- IPAM link-allocations: filter networks by proxmox_server_id and proxmox_node
  to prevent cross-server/cross-node IP assignment
- IPAM link-allocations: add manual server+network selection modal before linking
- IPAM add-network forms: add Proxmox server and node selectors with dynamic
  cluster-info loading (ipam_dashboard.html, ipam_networks.html)
- models.py / schemas.py: add proxmox_node field to IPAMNetwork
- migrations: migration #16 adds proxmox_node column to ipam_networks table
- Theme fixes: replace all hardcoded rgba/color:#fff/color:white with CSS vars
  across base.html, virtual_machines.html, instance_detail.html,
  os_templates.html, proxmox_vms.html, ipam_network_detail.html,
  ipam_allocations.html
- i18n: add proxmox_node, node selector, link-allocations modal keys (ru/en)
- Version bump: 1.0.4 -> 1.0.5
