refine position-sizing UI: top-of-panel controls, segmented risk, no spinners

The account/risk inputs are global "set once" settings, so they're moved out of
the panel body into a single compact line in the recommendation header. Replaced
the number-input spinners: risk % is now a segmented preset selector (0.5/1/2/3),
account size a clean text field with a $ prefix. Relabel "at risk" → "max loss".
