Migrated all 80 app JSON files to place config_path inside each
install_methods object instead of at the root level. This allows
different install methods (e.g. Debian vs Alpine) to have distinct
config paths.
Also updated AGENTS.md JSON structure example to reflect the change.
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.
