[Bug] Anthropic API Error: Rate limit reached at 12% weekly usage

Bug Description
Issue Summary:
API returning "Rate limit reached" error despite usage being only at 12% for the current week.
Expected Behavior:
API calls should succeed when usage is at 12% of weekly quota.
Actual Behavior:
All API calls are failing with "API Error: Rate limit reached" message.
Usage Details:

Current session: 0% used
Current week (all models): 12% used
Reset date: March 29, 12am (Europe/London)
Extra usage: Not enabled

Error Message:
API Error: Rate limit reached
Impact:
Unable to make any API calls despite having 88% of weekly quota remaining.
Steps to Reproduce:

Make API call to Claude (tested with simple "hello" prompt)
Receive rate limit error immediately
Check /usage dashboard showing only 12% usage

Additional Context:
The rate limit error appears to be triggering incorrectly - the usage dashboard clearly shows significant quota remaining, but all requests are being blocked as if limits were exceeded.
