Steve Coffey 31ffe2bc9a Fix retry classification for throttling and quota errors (#45602) ...

## Why

`slow_down` errors were treated as terminal server overloads, while exhausted credit balances and spend limits fell through to retryable stream errors.

## What changed

- Classify `slow_down` as a retryable rate limit in HTTP 503 responses and SSE failures, preserving the server message and parsing retry delays from SSE error messages.
- Map `credit_balance_exhausted`, `organization_spend_limit_exceeded`, and `project_spend_limit_exceeded` SSE errors to quota exhaustion so they terminate without retries.

## Testing

Extend tests to cover HTTP error classification and retryability, `slow_down` stream retry exhaustion and message-provided delays, and a single `UsageLimitExceeded` error with no retries for each quota error code.
