Add link editing, AI re-description, and footer

Links can now be edited manually (title, summary, category,
manufacturer, tags) via an inline edit form, with a "KI neu
beschreiben lassen" action that re-fetches the URL and lets the AI
regenerate all fields. Editing recomputes the search embedding.

Also adds an app footer showing author, version, and hostname.
