Update mini-qr manifest schema and metadata

Migrate manifest to the updated schema and enrich metadata: rename install_methods_json->install_methods and notes_json->notes, add categories, date_created, updateable, interface_port and default_credentials fields. Adjust description text (remove emoji) and set the install script path (ct/mini-qr.sh). These changes prepare the Mini QR package for the newer CT manifest format and include basic deployment metadata.
