Links can be bookmarked for a later look via a toggle button on the card (🏷️/🔖), shown with a yellow border while flagged. A new sidebar section "Merkliste" links to /?review=1, filtering to just the flagged links; the count updates live via the existing facets query. Since the project has no migration framework, add a minimal startup check that ALTER TABLEs in the needs_review column for existing SQLite databases (create_all only creates missing tables).
