Add settled balance panel, cash booking mode, and Kasse dashboard line

- Balance panel turns green with "Bezahlt ✓" + breakdown when open_balance <= 0, on all four tab pages (me, pay, staff_user, staff_pay)
- booking_mode radio on me.html and staff_user.html: normal / for_free / cash_paid; cash_paid auto-creates matching UserPayment(method=cash)
- Dashboard finance section shows "Kasse (bar)" sum of all cash payments for cross-checking
- staff_pay prefill lower-capped at 0; "Zahlung eintragen" always visible on staff_user
