feat(maria): profil de client (firma), asociat cu mai multe numere

Un client poate avea mai multi angajati care scriu pe WhatsApp de pe
numere diferite; toti gasesc acum acelasi profil (rag/client.py,
~/.maria-bridge/clients.json). Profilul intra in prompt sub o sectiune
DESPRE CLIENT, la fiecare mesaj, stateless ca restul Mariei — dar nu
atinge cautarea/scorul din rag/rank.py, ca sa nu strice pragurile deja
calibrate. Administrare din dashboard (sectiune noua "Clienti cunoscuti"),
nu din chat, ca sa ramana pe canalul autentificat.

117/117 teste maria-whatsapp-bridge + teste noi pentru rutele de dashboard.
