A queued export could not see the server, so its name check always
answered "free" and the upload PUT over whatever was there: Increment
and Skip behaved as Overwrite on Nextcloud, and two exports of the same
name queued before either uploaded landed on one file.
The batch now names around what the album records of earlier exports
and what the outbox already holds for that folder. The outbox record
carries the policy, and the drain lists each destination folder once
and applies it against what the server holds: Increment steps past a
taken name and re-points the album's row, Skip drops the entry. A
record without a policy (older builds, a merge's composite) is sent as
named, as before. The album is recorded before the drain starts so a
rename has a row to move.
