Jinwoo Hong 164c7140fd fix(relay): stop reporting an unavailable home cell as exhausted capacity (#21518) ...

A host whose home cell is not live — readiness false, drained, or inside a
boot window — is refused by the committed-fence branch in assignOnce()
without any capacity being consulted. It answered relay_capacity_exhausted,
so every cell boot and every readiness dip printed capacity rejections at
17% fleet utilisation and sent an investigation after headroom that was
never short.

The branch now raises RelayHomeCellUnavailableError, which carries the cell
id and which of cellIsLive()'s conditions failed (draining / booting /
unheard / not_ready). The director logs reason, cause and cell, and returns
the new reason in the same retryable 503. Nothing on the wire reads the
body: the desktop client discards it unread and branches on status only,
and no log-based metric or alert parses the reason. The load harness, the
only body-reading consumer, gets its own bucket so a home-cell rejection no
longer inflates the capacity count.

Hinted grants are now logged on whichever lane served them, so a host that
failed sticky verification and was rehomed by placement leaves a record of
where it landed. Unhinted placement grants stay silent.
