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".

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.

Fixes #1691

- pollOutbox() reused a 10s context for SetOutboxWatermark after event
  processing could take much longer, causing "outbox watermark write
  failed: context deadline exceeded". The watermark never advanced so
  the same 200 events were reprocessed every poll cycle, spiking CPU.
  Now uses an independent 5s context with up to 3 retries (200ms apart).

- When multiple Codex accounts sharing the same 21-22 groups are all
  rate-limited in quick succession, each account_changed event triggered
  redundant bucket rebuild attempts for the same groups. Introduce
  batchSeenKey{groupID, platform} and thread a seen map through the
  handler chain; rebuildBucketsForPlatform skips (group, platform) pairs
  already rebuilt within the same poll batch (~80% fewer rebuild calls in
  the 5-accounts-same-groups scenario).
