fix: fix bug with no refreshing date in chat on visibillity event

[Linhead]

Fixes #862

Fix: Dates in chats not refreshing when day changes while app is in background

Problem
When user opens a chat late at night (e.g., 23:55) and messages display "Today", then switches to another tab/app, and returns after midnight (e.g., 00:05), the dates still incorrectly show "Today" instead of "Yesterday" in chat page and in chat preview section as well . The dates only refresh when opening another chat and coming back or reload the page

Solution

• Added reactive dateRefreshKey that triggers component re-render on visibility change
• Used existing Visibility.change handler to update the key when app becomes visible
• Applied :key attribute to component for force re-render
• Utilized existing maintainScrollPosition() method to preserve scroll position during re-render

Test instructions

1. Change the system time to 23:55 or any other time close to midnight.
2. Send any message in any chat.
3. Verify that the message time in the chat and in chat preview is displayed as Today.
4. Minimize the tab or the browser.
5. After midnight (according to the system clock), return to the tab:
   • The sent message should now display the date as Yesterday in chat and chat preview section

Test results: Failed

Test instructions

1. Change the system time to 23:55
2. Send any message in a chat
3. Verify that the message time in the chat is displayed as Today
4. Minimize the browser
5. After midnight (according to the system clock), return to the browser
6. The message time in the chat is still displayed as Today

Switching tabs: Works partly. In chat, date is "Yesterday". But in chat list, it's still "Today".

To fix:

1. Listen "Minimize Browser/app" event, and update on restoring from background.
2. Update date not only in chat, but also in chat list
