feat: add clearProvisioningError functionality and restart team option

- Introduced clearProvisioningError method in team-related components to reset provisioning errors when dialogs open, enhancing user experience.
- Added onRestartTeam callback to ActivityItem and ActivityTimeline components for handling authentication errors, allowing users to restart teams directly from error messages.
- Updated various components to support the new functionality, improving error handling and team management interactions.
