[Bug] Twitter Mentions tab does not sync automatically until opened on official web

Summary

Twitter "Mentions" tab does not refresh automatically unless manually visited on the official web client.

Environment

• App Version: 1.7.4(5172)
• OS / Platform: Android 16
• Account Type: Twitter (via Web API login)

Steps to Reproduce

1. Receive a new reply/mention on Twitter.
2. Open Flare and check the Notifications section.
3. The "All" tab receives the notification correctly, but the "Mentions" tab does not show the new mention (remains stale even after pull-to-refresh).
4. Open the official Twitter web client in a browser and navigate to the "Mentions" tab once.
5. Go back to Flare and pull to refresh — the missing mentions now appear immediately.

Expected Behavior

The "Mentions" tab should automatically poll and sync new mentions alongside the "All" notifications stream, without requiring manual activation via the official web client.

Suspected Root Cause

It seems the background polling or refresh worker only queries the global notifications endpoint (notifications/all) and lacks independent periodic polling or unread cursor synchronization for the notifications/mentions endpoint.

Start by locating the Android notification polling or refresh worker and the code handling the notifications/all and notifications/mentions endpoints. Reproduce the stale Mentions tab behavior, then verify that new mentions appear after background polling or pull-to-refresh without visiting the official web client.
