feat: LXC container creation from CT templates

- Add LXC deploy API endpoints: GET /proxmox/api/lxc-templates/{id},
  GET /proxmox/api/lxc-storages/{id}, POST /proxmox/api/lxc/deploy
- Add ProxmoxClient.get_lxc_storage_templates() and get_node_storages()
- Fix duplicate create_lxc_container() — removed dead copy, updated
  canonical with nameserver/searchdomain params
- Fix wait_for_task(): accept WARNINGS:N exitstatus as success
- Add IPAM IP release on deploy failure
- Add frontend hooks: useLXCTemplates, useLXCStorages, useDeployLXC
  with 5-min staleTime caching
- Add LXC wizard steps to CreateInstanceWizard (type, template, config)
- Add LXC i18n keys to en.json and ru.json
- Add LXCTemplate and LXCDeployRequest TypeScript interfaces
