feat: keep version check in MSIX build, point update dialog at the Store

The update check is notification-only (OrcaSlicer never auto-downloads),
so the Store build keeps checking for new versions instead of skipping
the check. What changes when packaged is the new-version dialog: the
Download button is hidden, the info text asks the user to update from
the Microsoft Store, and the hyperlink / wxID_YES action opens the Store
product page instead of the GitHub release page.
