android: use saved chat endpoint in chats menu

android/CHANGELOG.md

@@ -634,3 +634,8 @@
 - Improved `chat_updated` handling in realtime flow:
   - now refreshes both active and archived chats lists to sync user-scoped flags (`pinned`, `archived`) immediately.
 - Added parser fallback for realtime chat events to support payloads with either `chat_id` or `id`.
+
+### Step 99 - Saved chat API parity
+- Added Android support for `GET /api/v1/chats/saved`.
+- Wired chats overflow `Saved` action to real backend request (instead of local title heuristic).
+- Saved chat is now upserted into local Room cache and opened via normal navigation flow.
