refactor(storage): guarantee vertical + full-width mode row layout

Replace the FormItemLayout wrapper for the both/either row with a
plain label + RadioGroupStacked stack — the previous default-vertical
FormItemLayout wrap was producing the correct DOM but the effect
wasn't visible depending on cache/reload state. Explicit
`flex flex-col gap-y-2 w-full` removes any ambiguity: label above,
radio group below, spanning the full section width.
