feat(team): enhance team messaging functionality and UI

- Integrated pending replies state management for team members.
- Updated TeamDetailView to initialize pending replies from state.
- Added logic to refresh team messages and member activity on tab focus.
- Improved UI components by increasing dialog content width for better layout.
- Enhanced member draft rows with avatar support for better visual representation.
- Implemented reconciliation logic for pending replies based on message history.
- Updated tests to cover new functionality and ensure reliability.
