message sending status

-   In `ConversationsScreen`, removed `isNeedToScrollToTop` and `onScrolledToTop`, and refactored toolbar container color logic. Added `NoItemsView` for empty conversation lists.
-   In `MainGraph`, added `onMessageClicked` for navigation to message history.
-   In `ApiEvent`, introduced `parseOrNull` for handling unknown event types.
-   In `ConversationsViewModel`, removed `scrollToTop` logic and refactored error handling.
-   In `FriendsViewModel`, refactored error handling and introduced `onErrorConsumed` and `handleError`.
-   In `FriendItem`, added an icon button to initiate sending a message to a friend.
-   In `strings.xml`, added or updated strings for session expiration, log out, refreshing, and empty friend lists.
-   In `RootScreen`, added `onMessageClicked` for navigating to messages.
-   In `FriendsList`, added `onMessageClicked` for handling message clicks.
-   In `MainScreen`, removed unused `MutableSharedFlow`.
-   In `FriendsScreen`, added support for showing errors, added `onMessageClicked`, and replaced `hazeChild` with `hazeEffect` and `hazeSource`.
-   In `FriendsNavigation`, added `onMessageClicked` for handling message clicks.
-   In `ConversationsNavigation`, removed the unused `scrollToTopFlow` parameter.
-   In `ErrorView`, added text alignment.
-   In `NoItemsView`, added support for a button and custom text.
-   In `LongPollUpdatesParser`, replaced try-catch with `parseOrNull`.
