rcourtman f0a356c016 fix: ZFS pool usage now includes zvols and all pool consumers ...

The previous reconciliation logic (issue #1052) used per-dataset statfs
values for Total and Used. On Proxmox systems, statfs on a mounted
dataset (e.g. rpool/ROOT/pve-1) only reports that dataset's own usage,
completely missing zvols (VM disk images) and other datasets. This caused
storage bars to show ~0% usage (a few GB of OS files) when the pool
actually had terabytes of VM data allocated.

Fix: derive usable pool capacity from the ratio of dataset Free (usable
pool-available from statfs) to zpool Free (raw pool-available from zpool
list). This ratio converts raw zpool Size to usable total, and Used is
computed as Total - Free. This captures all pool consumers including
zvols, handles RAIDZ parity overhead and mirrors uniformly, and produces
correct usage percentages.

Verified with tests for RAIDZ, mirrors, and both with zvols present.
