Jinwoo Hong fa0010e8d6 fix(relay): abort rehomes whose host never arrived, without disabling the switch (#21813) ...

A regional rehome whose host went offline right after accepting the move
left its migration row open forever: the target had registered it, the host
held nothing on the source, and the completion sweep could never finish it.
Eight such rows filled REGIONAL_REHOME_CONCURRENT_LIMIT and every later
candidate came back deferred, silently, for 21 hours.

The only sweep that touched them fires at 24 hours and also sets
enabled = 0 on the durable control, so the first leak to age out would have
turned rehoming off, repeatedly.

Adds a director sweep that rolls such an attempt back to its source after
one migration lease, with abort_reason = 'host_not_arrived', reusing the
existing rollback (assignment epoch bump back to the source, lease removal,
superseded target reservation release) and leaving the switch untouched.
The 24-hour sweep keeps its disable as a last-resort latch.

The source cell now names why it deferred, on a new optional response field,
and the director stops walking its candidate page on a deferral no later
candidate can pass. Each poll that dispatched logs one summary line.
