fix(dashboard): explizite zwei-zeilen-layout für suchbox

- FastAPI: parse_engram now includes link_suggestions and predictive_links from metadata
- FastAPI: add POST /api/links/accept to create links from suggestions
- Dashboard: new renderCardsWithSuggestions() displays suggestions in each card
- Dashboard: acceptLink() function handles click-to-link
- Dashboard: loadCards() calls renderCardsWithSuggestions()
- Systemd: remove DirectoryNotEmpty from ingest path unit (already present)
