Replace all legacy dotted permission codes (vms.view, proxmox.manage, ...)
in PermissionChecker/has_permission across app/api with the new
resource:action format (vm:view, server:manage, ...), per LEGACY_PERMISSION_MAP.
All 33 codes used by the API are now registered in the permission registry.
Also switch the /api/auth/me admin branch to get_all_permissions_v2 so the
endpoint emits permissions in the new format only.

Three related fixes so login/password/SSH key/IP survive a reinstall:
1. backend/app/api/proxmox/lxc.py — on initial LXC deploy save
cloud_init_user='root' and cloud_init_password=req.password to VMInstance
(previously both were None, so reinstall could not restore root password).
2. backend/app/api/proxmox/async_ops.py — _do_reinstall_sync passes
cached.cloud_init_password to create_lxc_container so the new container
gets the same root password as the original.
3. backend/app/workers/monitoring_worker.py — VM sync worker no longer
overwrites VMInstance.ip_address with NULL when no IPAM allocation
exists for that (server_id, vmid). It only updates the field when
IPAM has a value, otherwise the IP saved at deploy/wizard time is
preserved.
