queue-table: Outbound › Queue as the drawn table, Inbound › Queue built

Owner, 2026-10-18: "Фиаско, что очередь не была сделана. Как мы это
допустили? Исправляем!" The mockups out-queue and in-queue (design 629de5e,
guards 8525e8e).

- postfix: postqueue -j gives each message's size and each recipient's
  delay_reason (src/postqueue/showq_json.c, format_json(): "delay_reason"
  only when LEN(why) > 0); QueueListing reads it with the page's 5 s,
  QueueMessages keeps the notifier's 30 s.
- view: one Queue page type for both directions (queue.go), one polled box
  (queue_body.html): a row per recipient, oldest first, cut at 200 with a
  foot; the head "N messages · size", "Refreshes on its own" while empty;
  Last reply is the delay reason, or where the message is (active, hold,
  incoming) before there was one. Inbound has no Details: an inbound
  message has no page of its own.
- handlers: one read of the queue, split by the recipient's domain against
  the inbound domains; an outbound recipient is linked to its send-log row
  (store.SendLogRefsByQueueID, through idx_send_log_queue_id, plan pinned in
  TestSendLogQueriesUseTheirIndexes), matched without regard to case, else
  the message's first row. Both pages are the global role's; the inbound
  one 404s with the relay off. Routes /inbound/queue (+ /fragment), menu,
  touch menu and sibling strip.
- Overview: Queues · Both empty · outbound and inbound with the relay on.
- Help: the queue topic rewritten, an Inbound queue topic (word for word with
  the mockup; domain administrators do not see it, as with the lists).
- TestUnbuiltScreensAreOnTheRoadmap and its rule in development.md: an
  exempted screen must be named in roadmap.md; queue-table leaves the
  roadmap; guide, architecture, panel-redesign.md updated.

Tests: go vet; go test ./internal/web/... ./internal/store ./internal/postfix
./internal/notify pass.
