archipelago 2a26576dbd fix(specs): measure DISK_GB at /var/lib/archipelago, not / ...

The reconcile spec for bitcoin-knots auto-enables prune=550 when
DISK_GB < 1000. DISK_GB was measured via `df /`, which on every
archy install reports the ~30 GB OS partition because user data
lives on a separate encrypted /var/lib/archipelago volume.

Result: every archy node with a 2 TB data drive was silently being
configured as a pruned node, and any bitcoin-knots container
recreated by reconcile would delete its historical blocks down to
the 550 MB prune window on next start.

Observed on .228 (2 TB box): blocks dir went from 384 GB to 926 MB
after a reconcile-triggered restart. Historical archive unrecoverable
without full re-IBD from genesis.

Fix: check /var/lib/archipelago first (where bitcoin data actually
lives). Fall back to / only on first-boot before the data partition
is mounted.
