feat: integrate MokoGitea license system for update checks

Update server now points to MokoGitea's dynamic endpoint which
validates license keys (dlid) and generates update XML from git
releases. Users enter the download key via Joomla's native
System → Update Sites interface. Legacy static URLs are auto-migrated
on install/update.
