audit 4: a deleted domain says so, the Outbound log filters by status and day

L17: past DeleteDomain both rebuilds run, their errors joined under
domain.ErrDeletedIncomplete; the key is removed only when OpenDKIM's tables
were rebuilt (they may still name it otherwise); the domain list says the
domain is deleted and that Reload configuration finishes it, not "internal
error". Tests in domain (the tables failing, the sender map failing) and
handlers.

The Outbound log's status and day filters (owner, 2026-10-13; the mockup
first, 80e3979): view.OutLogFilter carried by the poll, the pages, the rows'
links and the message's way back; SendLogFilter.Status, Since, Until (whole
UTC days, as the Inbound log's); rejected is the three refusals together; a
status not in the list is no narrowing. Tests: the filters through the
handler, the poll and the way back; the day boundaries in store.

The plan's milter-socket step is ticked: done in 2.5.2 (98e09fe).

Tested on the test server: go vet + go test of 25 packages, make e2e (all
pass, 642 s) on this tree.
