fix: update mainWindowRef on window close/recreate, remove dead code

- Add teamProvisioningService.setMainWindow(null) in window close handler
- Add teamProvisioningService.setMainWindow(mainWindow) in window recreate
  Without this, notification click focused destroyed window instead of new one
- Remove unused dismissAllApprovalNotifications (cleanupRun uses per-requestId dismiss)
