fix: flaky WebSocket test, usage request queue, and test improvements
- Fix flaky WebSocket passthrough test: allow StatusNormalClosure after
client close instead of requiring NoError (race condition fix)
- Fix ratelimit 401 test: use PlatformOpenAI instead of PlatformGemini
for OAuth token cache invalidation scenario (more accurate)
- Add usageLoadQueue: Anthropic OAuth/setup-token accounts sharing the
same proxy exit are serialized with 1-2s jitter to prevent upstream 429
- AccountUsageCell: add module-level usage cache (5min TTL), unmounted
safety guard, and integrate enqueueUsageRequest for throttled fetching
