Follow-up to #133283 (greptile review). Store records are keyed by the
resolved store path, but the notice sender rebuilt the owning profile from
that path's parent. A profile whose cron/ is a symlink to another disk has
a foreign parent, so neither its outage nor recovery notice reached any
home channel; forget_homes had the same mismatch and never dropped such a
departed profile's record.
Both now match by resolving each served home's own cron/ path.
