feat(logging-p0): add ErrorBoundary and replace remaining console.* with logger

Add React ErrorBoundary component that captures rendering errors with
full component stack and logs them to main process via IPC. Wrap all
three App branches (PlaywrightDownload, UnauthenticatedApp,
AuthenticatedApp) with scoped boundaries.

Replace 13 console.* calls across renderer with structured logger:
- useDialogFocus: 10 calls (focus management diagnostics)
- PlaywrightDownloadDialog: 1 call (download cancellation error)
- useReportData: 1 call (report fetch failure)
- parser: 1 call (execution time extraction warning)
