Wiki.js: install 3.x

Wiki.js 3 lives in requarks/wiki, needs Node.js 26 and creates its own ltree and pg_trgm extensions in the wiki schema, and starts with node --no-experimental-webstorage backend. dataPath moves out of the app folder, which every update replaces; the admin password is generated and saved to ~/wikijs.creds. Updates follow upstream's guide and put Puppeteer back when it was installed. 2.x containers keep getting 2.x updates from requarks/wiki-v2, since 3.x cannot upgrade them in place, and are told how to export and import.
