Bug: crm_v2.html, admin_users.html, ostali pozivali /api/v2/auth/me
koji ne postoji u backendu (postoji /api/auth/me bez v2).
401 redirect na /login?reason=unauthorized iako Damir prijavljen.
Fix:
- Frontend: replace /api/v2/auth/me → /api/auth/me u svim file-ovima
- Backend: dodan defensive alias @app.get('/api/v2/auth/me')
