- New Outbox screen lists queued messages with status (Queued, or "Couldn't send" in
red after a failed attempt), an app-bar Retry, and a per-message cancel.
- The inbox shows an "Outbox (N)" entry while anything is queued. Repository gains
observeOutbox/cancelOutboxMessage/retryOutbox; OutboxDao.observeAll + OutboxMessage.
- SendScheduler now enqueues the drain with REPLACE rather than APPEND_OR_REPLACE so
newly-queued mail and manual retries run promptly, overriding a pending retry-backoff
(previously a queued message could sit behind an exponential backoff for minutes).
- assemble/test/lint green; verified on the Android 17 emulator — a message stuck from an
earlier offline send showed as failed in the outbox, and tapping Retry (server back up)
drained it to "Outbox is empty".
