fix (ui/volumes): herstel container-koppeling via inspect endpoint

containers-dashboard geeft Mounts als strings (destination paden).
Volledige mount-info (Type + Name) zit alleen in /containers/inspect/{name}.

Fix: voor containers met niet-lege Mounts parallel inspect ophalen,
daarna filteren op Type === "volume" voor named volume koppeling.

Getest: postgresdb_data → postgres-db, n8n_data → n8n.
