   - unregister token on logout,
   - handle foreground push payload via existing notification service worker.
 - Added required env keys to `web/.env.example` and backend Firebase env keys to root `.env.example`.

+### Step 106 - Unread counter stabilization in Chat screen
+- Fixed read acknowledgement strategy in `ChatViewModel`:
+  - read status is now acknowledged by the latest visible message id in chat (not only latest incoming),
+  - delivery status still uses latest incoming message.
+- This removes cases where unread badge reappears after chat list refresh because the previous read ack used an outdated incoming id.
