23-Jun-2026 — real message-time ordering, reconnect button, and mobile density #293

build 719 — commit 2d74e56

• Conversation list and thread messages now sort by the message's actual receivedAt/sentAt rather than the time it was imported. Thread firstSeenAt/ lastSeenAt are derived from the message time with $max/$min so the latest and earliest message win regardless of import order. Previously every imported thread carried the import timestamp, which displayed the wrong time and made the ordering meaningless.
• Promoted the Newest/Oldest sort toggle to the top button row so one control governs both the conversation list and the messages within a thread.
• Added a Reconnect button on a connected Gmail mailbox so a revoked or expired token can be re-authorised in place, preserving the mailbox settings and the Pub/Sub watch. The connect button previously only appeared when no token was stored, leaving no way to reconnect a mailbox whose token had died.
• Mobile: hide the redundant Conversations heading and the count line (shown only while searching), give the scrollable list more height, and make the search box padding symmetric.
