fix(restore-gui): surface registry-backup load failures to the user

Browse Source 
Picking a malformed or invalid backup .json in the Restore Backup dialog threw out of the WPF button-click handler. Because the throw originates inside a dispatcher callback, it bypassed every surrounding try/catch (those sit on a different call stack than the dispatcher-invoked handler) and was caught only by the dispatcher's global unhandled-exception handler, which writes a console warning and marks it handled -- invisible in the GUI. The dialog just sat there doing nothing. Wrap the load + overview render in try/catch and show the error via the existing Show-MessageBox helper, matching the convention already used in this file.
