[BUG] /usage command fails with rate_limit_error when checking usage data

What's Wrong?
When running the /usage command to check current usage and limits in Claude Code, the UI displays an error:

Error: Failed to load usage data: {"error":{"message":"Rate limited. Please try again later.","type":"rate_limit_error"}}

The /usage dialog opens but immediately fails to load any data, making it impossible to monitor current token usage or remaining quota.

What Should Happen?
The /usage dialog should successfully load and display current session usage statistics, token consumption, and remaining quota without being rate limited by the usage data endpoint itself.

Steps to Reproduce

1. Open Claude Code in an active session
2. Type /usage and press Enter
3. Observe the error: "Error: Failed to load usage data: rate_limit_error"

Additional Context
This appears related to #31637 where the /api/oauth/usage endpoint aggressively rate limits usage monitoring requests. The error occurs on the Anthropic Max plan.
