Merge branch 'origin/main' into nightly

Resolve 4 conflicts:
- relay/compatible_handler.go: accept main's refactor (postConsumeQuota -> service.PostTextConsumeQuota)
- service/quota.go: accept main's PostClaudeConsumeQuota deletion, keep nightly's tiered billing in PostWssConsumeQuota and PostAudioConsumeQuota
- web/src/i18n/locales/{en,zh-CN}.json: merge both sets of translation keys

Post-merge integration:
- Add tiered billing (TryTieredSettle, InjectTieredBillingInfo) to PostTextConsumeQuota
- Update tool pricing calls to use nightly's generic GetToolPriceForModel/GetToolPrice API
