 - Updated multi-select top actions/menu to be closer to Telegram reference in wording.

+### Step 97 - Chats popup/select actions wired to backend API

+  - `archive/unarchive`
+  - `pin-chat/unpin-chat`
+  - `clear`
+  - `delete (for_all=false)`
+  - `chat notifications get/update`
+- Added repository methods and `ViewModel` actions for those operations.

+  - mute/unmute selected chats,
+  - archive/unarchive selected chats,
+  - pin/unpin selected chats,
+  - clear selected chats,
+  - delete selected chats for current user.
