docs(ep0): hub PBS-DR capacity gauge verified correct after the volume move

Browse Source 
The last open item from the datastore relocation. Hub operator UI
(Offsite -> PBS DR) reports felhom-offsite (ep0) at 97.9 GB capacity,
12.6 GB used, 13% full - agreeing with the on-box df (98 G / 13 G / 13%).

The gauge follows the datastore's CONFIGURED PATH, so the relocation
required no hub-side change. RUNBOOK section 10.3 warned that a stale
37.2 GB reading would mean the gauge reads the wrong filesystem and
would be a real bug worth a roadmap item - it does not, and there is
no bug.

2. **GC not run** — now unblocked by the round-trip, but left for a separate deliberate run. No GC
schedule is configured on this PBS at all.
3. **Hub PBS-DR capacity gauge not re-read** — the hub is a ClusterIP service and was not reachable
from DooPlex. If it still reports 37.2 GB it is reading the wrong filesystem: a real bug.

(Offsite → PBS DR) reports `felhom-offsite (ep0)` at **97.9 GB capacity, 12.6 GB used, 13 % full**,

needed no hub-side change and the suspected "wrong filesystem" bug does not exist.
4. **ep0 has no swap** (temporary 4 GB file removed; box left as found). Worth a small permanent
swapfile — outside this runbook's scope.
