fix: manager progress toast and install button UX issues (#10423)

## Changes

- Reset `isRestartCompleted` in `closeToast()` so the "Apply Changes"
button appears correctly on subsequent installs instead of skipping to
the success message
- Add `@click.stop` on `PackInstallButton` to prevent click from
bubbling up to card selection, which was unintentionally opening the
right info panel
