FIX: Unread count could disagree with the /unread topic list (#40473)

committed 02:07PM - 02 Jun 26 UTC

The "Unread (N)" badge could count a topic that did not appear on the /unread pa…ge (and, conversely, a genuinely unread topic could be hidden from /unread). See https://meta.discourse.org/t/-/403986. Both the count and the list bound their results by the user's "old unread" cutoff, `user_stats.first_unread_at`, which is computed from `topics.updated_at`. The count (TopicTrackingState) filters on `topics.updated_at >= first_unread_at`, but since 17555ae8798 (#40127) the /unread list (TopicQuery#apply_max_age_limit) filtered on `topics.bumped_at` instead. A small action at the tail of a topic (close, auto-close, category change, ...) moves `updated_at` but not `bumped_at`, so such a topic passed the count's filter yet failed the list's filter: it was counted but never listed. #40127 switched to `bumped_at` for suggested topics, where bounding by last visible activity is the desired behaviour, so reverting it is not an option. Instead, `apply_max_age_limit` now takes an explicit `age_column` that defaults to `updated_at` (keeping the unread and new lists consistent with the count), and the suggested-topics callers pass `age_column: :bumped_at` to preserve their behaviour.
