✨ style(Account UX): resilient binding layout, copyable popovers, pastel header, and custom pay colors
- AccountManagement.js
- Prevent action button from shifting when account IDs are long by adding gap, min-w-0, and flex-shrink-0; keep buttons in a fixed position.
- Add copyable Popover for account identifiers (email/GitHub/OIDC/Telegram/LinuxDO) using Typography.Paragraph with copyable; reveal full text on hover.
- Ensure ellipsis works by rendering the popover trigger as `block max-w-full truncate`.
- Import Popover and wire up `renderAccountInfo` across all binding rows.
- UserInfoHeader.js
- Apply unified `with-pastel-balls` background to match PricingVendorIntro.
- Remove legacy absolute-positioned circles and top gradient bar to avoid visual overlap.
- RechargeCard.jsx
- Colorize non-Alipay/WeChat/Stripe payment icons using backend `pay_methods[].color`; fallback to `var(--semi-color-text-2)`.
- Add `showClear` to the redemption code input for quicker clearing.
Notes:
- No linter errors introduced.
- i18n strings and behavior remain unchanged except for improved UX and visual consistency.
