Proxmox's guest-agent exec (PVE/QemuServer/Agent.pm) dies with
"Wide character in subroutine entry" when input-data contains non-ASCII
bytes. The growpart script had Cyrillic comments, so the whole auto-grow
call returned 500 and the FS was never resized. Replace those comments
with ASCII so the script reaches the guest.

Backend fixes for VM/LXC disk resize:
- resize_vm_disk/resize_container_disk now honor wait_for_task and raise
the real Proxmox exitstatus (e.g. "disk 'scsi0' does not exist") instead
of always returning success.
- add grow_vm_filesystem: after a VM resize, rescan the disk (retry loop,
needed for SATA/SCSI), growpart the partition and resize the FS
(ext*/xfs/btrfs) via the guest agent; surface its output to the API.
- execute_script normalizes CRLF/CR to LF so pasted scripts and growpart
don't break on trailing \r ("partition-number must be a number").

Add live per-disk usage, disk read/write and network in/out rates to the
instance Overview tab, the instances list and the dashboard top-loaded list.
Backend:
- get_vm_fsinfo() pulls per-filesystem usage via QEMU guest agent
- metrics_broadcaster computes I/O rates (bytes/sec) from cumulative counters
- instances-list loop now refreshes each running VM via status/current
(1s-granular) instead of cluster/resources (10s pvestatd), with bounded
concurrency, and paces both realtime loops to a 1s cadence
Frontend:
- OverviewTab: per-disk cards, Network I/O and I/O-rate cards via WS
- InstancesPage: Net and Disk I/O columns; Disk% shown for LXC only
- DashboardPage: top-loaded list overlaid with realtime metrics
