Review follow-ups on e5363a6:
- MigrateSettingsOrg no longer guesses via the "default" slug. One org
means stamp that org; zero orgs means synthesise Default; more than
one means leave it alone and log, since guessing would hand one org
another's SMTP config and ESO token.
- EnsureSettingsIndexes failure is now fatal. Without the unique index
on org_id, GetSettings returns an arbitrary duplicate; without the one
on the token hash, ResolveSecretsReadToken picks an arbitrary org.
- Name the token-hash index explicitly so it stops colliding with the
legacy name DropOne targets, and exclude the empty string from the
partial filter.
- Log retention: distinguish a missing run doc from a Mongo error, so a
transient failure skips the directory rather than purging it at the
30-day default.
- Offline sweep: fresh context per org, log-and-continue on a per-org
error, plus a final pass for servers whose org no longer exists.
- ESO handler 401s on an empty token-derived org rather than querying
org_id "".
