feat: supply card metrics — replace Prestige with Anfragen count

Senior property manager perspective: the three key metrics are
Fläche (size), Frei ab (availability date), and Anfragen (active
inquiry count). Anfragen box highlights amber when > 0. Rename
Datenkonfidenz → Datenvollständigkeit (clearer for the manager).
Remove ÖV chip, keep fit-out and contract chips as property specs.
Wire inquiryCount from useActiveInquiries in Properties page.
