fix(platform): pass tier to get_usage_status() in reset_copilot_usage endpoint

The reset_copilot_usage endpoint was calling get_usage_status() without
the tier parameter, causing the response to always report STANDARD tier
regardless of the user's actual tier. Pass _tier from get_global_rate_limits()
to both get_usage_status() calls in the endpoint.
