💳 feat(TopUp): unify payment cards, add header stats, brand icons, and mobile refinements [[memory:5659506]]

- Add RightStatsCard and place it in RechargeCard header
  - Shows current balance, historical spend, and request count
  - Mobile: stacks under title; three metrics split equally (flex-1); vertical dividers hidden on small screens
  - Remove extra margins; small card styling

- RechargeCard
  - Replace redeem code Input icon with Semi UI IconGift
  - Style “Payable amount” number in red and bold; keep same style in confirm modal
  - Always render payment methods as Cards (remove Button variant) with adaptive grid
  - Use brand color icons: SiAlipay (#1677FF), SiWechat (#07C160), SiStripe (#635BFF)
  - Replace Stripe icon with SiStripe
  - Integrate RightStatsCard props; adjust header to flex-col on mobile and flex-row on desktop
  - Hide Banner close button when online top-up is disabled (closeIcon={null})

- InvitationCard
  - Simplify to match RechargeCard’s minimalist slate style
  - Use Card title for “Rewards” and place content directly in body
  - Improve link input and copy button; use Badge dots for bullet points

- TopUp index
  - Remove separate right-column stats card; pass userState and renderQuota to RechargeCard

- Cleanup
  - Lint passes; no functional changes to APIs or business logic
