refactor(messageThunk): streamline loading state management for topics (#7809)

* refactor(messageThunk): streamline loading state management for topics

- Reintroduced the handleChangeLoadingOfTopic function to manage loading states more effectively.
- Updated thunk implementations to ensure loading state is correctly set after message processing.
- Removed commented-out code for clarity and maintainability.

* fix(messageThunk): ensure loading state is managed correctly after message sending

- Added a finally block to guarantee that the loading state is updated after the sendMessage thunk execution.
- Removed commented-out code for improved clarity and maintainability.
