docs: reconcile the backlog with the user's notes, open 89 to 92

The 2026-08-15 pass over ~/Documents/Obsidian/note/notes on qtmaildir.md
found four entries with no item here, and one already-closed item with a
case that was never verified by hand.

89: runAutoSync() returns without re-arming the timer when a sync is
already in flight, so an edit made after the running mbsync passed that
account waits for a manual sync or cron. The second half of the same
complaint, rows leaving the list mid-interaction, is a design question
and is recorded as one rather than guessed at.

90: runSavedQuery() clears the account box for a query that names no
account. The line is deliberate and its comment says why, so this needs
a decision rather than a fix.

91 and 92 are unspecified, as the notes themselves say.

Item 66's row gains the one case its fix should already cover: a
single-message id: query whose card would not open is the same empty
MessageIdRole failure, unverified against an id: query.
