✨ 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.
