fix: remove excessive min-height gap in staking product cards

The Chakra→Tailwind migration translated `minHeight={75}` directly to
`min-h-75`, which resolves to ~300px (75 × 0.25rem) and reserved a large
empty gap below the platform/UI badges in every staking product card.
Grid layout already equalizes card heights and `mt-auto` keeps the
footer aligned, so no min-height is needed.
