[Bug] 使用记录页面，Tooltip 不显示缓存创建

Thank you for reporting this issue.

Analysis:

I've identified the root cause of this bug. The Cache column displays cacheCreationInputTokens as the total cache creation value, but the Tooltip shows a breakdown of cacheCreation5mInputTokens (5-minute cache) and cacheCreation1hInputTokens (1-hour cache).

Potentially affected code:

• src/app/[locale]/dashboard/logs/_components/usage-logs-table.tsx (lines 236-267) - Non-virtualized logs table
• src/app/[locale]/dashboard/logs/_components/virtualized-logs-table.tsx (lines 411-441) - Virtualized logs table

Root cause:

When the upstream API returns only cache_creation_input_tokens without the detailed breakdown (cache_creation.ephemeral_5m_input_tokens or cache_creation.ephemeral_1h_input_tokens), the system cannot populate the 5m/1h fields. The response parsing logic in src/app/v1/_lib/proxy/response-handler.ts (lines 1278-1335) handles both nested and flat formats, but if the provider doesn't supply the detailed breakdown, only the total is available.

Currently, the Tooltip always displays the 5m/1h breakdown even when this data is not available:

<TooltipContent align="end" className="text-xs space-y-1">
  <div className="font-medium">{t("logs.columns.cacheWrite")}</div>
  <div className="pl-2">
    5m: {formatTokenAmount(log.cacheCreation5mInputTokens)}
  </div>
  <div className="pl-2">
    1h: {formatTokenAmount(log.cacheCreation1hInputTokens)}
  </div>
  ...
</TooltipContent>

Expected behavior:

When the 5m/1h breakdown is not available but cacheCreationInputTokens has a value, the Tooltip should either:

1. Show the total cache creation tokens without the 5m/1h breakdown
2. Or indicate that the breakdown is unavailable

To help diagnose this further, please provide:

• Which provider is being used (direct API or relay)
• Whether this happens with all requests or specific providers only
