Force dropdown height to match the Model textbox

Reason: previous rule only hit [data-testid="dropdown"], but Gradio 5
also emits .gradio-dropdown with inner .wrap/.wrap-inner wrappers that
set their own small min-height, leaving the control visibly shorter
than the neighbouring textbox. Broaden selectors and pin both the
outer block and inner wrapper to 46/44px.
