[Bug] Claude Code charges additional usage despite available session and weekly quota capacity

Bug Description
Claude Code triggers paid "Additional Usage" even though my session limit (42% used) and weekly limit (32% used) have plenty of capacity remaining. The additional usage budget of 15€ was exceeded (108%, 16,17€ charged) while session and weekly limits were well within bounds. Claude Code should use the included subscription capacity first before charging additional usage. This appears to be a bug. I request a refund of the 1,17€ overcharge and a fix for this behavior.
