* feat: surface ZFS ARC reclaimable as dashboard context line

Add arcReclaimable to the HostMemory interface and MemoryWire shape so
the reclaimable ARC amount computed by readReclaimableArc() is exposed
through /api/system/stats and /api/fleet/overview. Show it as a context
line on the dashboard memory tile, matching the balloon pattern.

ARC continues to feed the gauge percentage as before; this is a
display-only addition for operator visibility.

* docs: clarify ARC line requires nonzero reclaimable, not just readable stats
