docs(payment): add Kyren Topup as international EasyPay provider option

Restructure the EasyPay recommendation block to present two options side
by side so users can pick by funding channel and settlement currency:

- Domestic / CNY — ZPay: official Alipay/WeChat API with 1.6% fee and
  T+1 automatic settlement (existing recommendation, expanded with fee
  and settlement details).
- International / USDT or USD — Kyren Topup (https://kyren.top): global
  payment stack supporting WeChat Pay and Alipay with local-currency
  checkout, USD settlement, and USDT/USD withdrawal. Fees: WeChat 2%,
  Alipay 2.5%, withdrawal 0.1% ($40 min / $150 max). Fills the gap for
  users who cannot use domestic Chinese channels or tolerate Stripe's
  6%+ fees.

Both recommendations share a single disclaimer at the end. The Chinese
heading uses "易支付" while the English one keeps "EasyPay".

fix：修复上游账号为OpenAI API key时Claude Code调用缓存率低的问题

refactor: extract ReadUpstreamResponseBody to deduplicate response read + too-large handling

fix: fix outbox watermark context expiry and add in-batch group rebuild dedup

Each retry in the SetOutboxWatermark loop now gets its own 5s context.
Previously a shared context could already be expired when the second or
third attempt ran, making the retries pointless.
