refactor: streamline team data service and enhance change review logic

- Removed unnecessary member metadata retrieval in TeamDataService to simplify task handling and prevent self-notifications for lead-owned tasks.
- Updated lead owner validation to ensure consistent case handling.
- Introduced a new reference in ChangeReviewDialog to manage in-flight file operations, preventing duplicate actions during file rejection.
- Enhanced changeReviewSlice to return null for invalid states, improving error handling and state management.
