Reviewer's GuideThis PR defers starting the notification expiration timer until a bubble is actually inserted into the UI model, wiring a new bubbleDisplayed signal through BubblePanel to NotificationManager, which now schedules timeouts based on the stored client expire timeout only when notifications are displayed, with thread-safe forwarding from the applet and added unit tests.

The notification expire timer previously ran in the notification server (worker thread) and was started when the notification was received, so a notification waiting in a long display queue could expire before its bubble was shown. The timeout is now owned by the bubble frontend and only starts once the bubble is actually displayed. 1. Add a per-bubble single-shot QTimer in BubbleModel that starts when a bubble is shown (insert/replace) using the client expireTimeout (0: never expire, -1: 5000ms default, Critical urgency: never expire). 2. On expiry the frontend closes the bubble and calls notificationClosed(id, bubbleId, Expired) on the server, which moves the notification from the in-memory store to the center database and emits NotificationStateChanged(Processed) and the DBus NotificationClosed signal. 3. Move the hover block to the frontend: setBlockedId pauses/resumes the per-bubble timer so hovering keeps the bubble on screen, keeping the 1s grace after unhover and the replaced-bubble blocking behavior. 4. Remove the server-side timeout bookkeeping: notificationDisplayed, setBlockClosedId, pushPendingEntity, onHandingPendingEntities, removePendingEntity and the pending-timeout QTimer. 5. Expose BubbleItem::timeout() and NotifyEntity::timeout() for the frontend timeout computation. 6. Remove the obsolete NotificationDisplayed/SetBlockClosedId tests. Log: Fixed notifications expiring before their bubble was displayed. Influence: 1. Send several notifications at once and verify each bubble stays for the full expire timeout. 2. Verify critical notifications and expireTimeout 0 never close. 3. Hover a bubble and verify it does not expire, then closes 1s after unhover. 4. Verify expired bubbles are moved to the notification center and the DBus NotificationClosed(Expired) signal is emitted. 5. Run the notification server unit tests. fix: 将通知过期计时迁移到气泡前端 通知过期计时此前在通知服务器（工作线程）中运行，收到通知时即启动，导致 长显示队列中的通知可能在显示前就已过期。现将超时逻辑交由气泡前端持有， 气泡真正显示后才开始计时。 1. 在 BubbleModel 中为每个气泡增加单次 QTimer，气泡显示（插入/替换）时 根据客户端 expireTimeout 启动（0：永不过期，-1：默认 5000ms，Critical 优先级：永不过期）。 2. 到期后前端关闭气泡并调用服务器 notificationClosed(id, bubbleId, Expired)，将通知从内存存储迁移到通知中心数据库，并发送 NotificationStateChanged(Processed) 与 DBus NotificationClosed 信号。 3. 将悬停阻塞移到前端：setBlockedId 暂停/恢复对应气泡定时器，使悬停时 气泡不关闭，并保留取消悬停后 1s 缓冲及替换气泡继续阻塞的行为。 4. 移除服务端超时簿记：notificationDisplayed、setBlockClosedId、 pushPendingEntity、onHandingPendingEntities、removePendingEntity 以及 pending-timeout 定时器。 5. 为前端超时计算暴露 BubbleItem::timeout() 与 NotifyEntity::timeout()。 6. 移除过时的 NotificationDisplayed/SetBlockClosedId 测试。 Log: 修复通知在气泡显示前就过期的问题。 Influence: 1. 一次性发送多条通知，验证每个气泡都能保持完整的过期时间。 2. 验证 Critical 通知与 expireTimeout 为 0 的通知永不过期。 3. 悬停气泡验证其不关闭，取消悬停 1s 后关闭。 4. 验证过期气泡进入通知中心，并发出 DBus NotificationClosed(Expired)。 5. 运行通知服务器单元测试。 PMS: BUG-372279
