✨ refactor: unify layout, adopt Semi UI Forms, dynamic presets, and fix duplicate requests

- Unify TopUp into a single-page layout and remove tabs
- Replace custom inputs with Semi UI Form components (Form.Input, Form.InputNumber, Form.Slot)
- Move online recharge form into the stats Card content for tighter, consistent layout
- Add account stats Card with blue theme (consistent with InvitationCard style)
- Remove RightStatsCard and inline the stats UI directly in RechargeCard
- Change preset amount UI to horizontal quick-action Buttons; swap order with payment methods
- Replace payment method Cards with Semi UI Buttons
  - Use Button icon prop for Alipay/WeChat/Stripe with brand colors
  - Use built-in Button loading; remove custom “processing...” text
- Replace custom spinners with Semi UI Spin and keep Skeleton for amount loading
- Wrap Redeem Code in a Card; use Typography for “Looking for a code? Buy Redeem Code” link
- Show info Banner when online recharge is disabled (instead of warning)

TopUp data flow and logic
- Generate preset amounts from min_topup using multipliers [1,5,10,30,50,100,300,500]
- Deduplicate /api/user/aff using a ref guard; fetch only once on mount
- Simplify user self fetch: update context only; remove unused local states and helpers
- Normalize payment method keys to alipay/wxpay/stripe and assign default colors

Cleanup
- Delete web/src/components/topup/RightStatsCard.jsx
- Remove unused helpers and local states in index.jsx (userQuota, userDataLoading, getUsername)

Dev notes
- No API changes; UI/UX refactor only
- Lint clean (no new linter errors)
