fix: optimize Claude Console quota exceeded status display

- Keep account status as 'active' when quota exceeded (not 'quota_exceeded')
- Keep isActive as true, only use quotaStoppedAt to mark quota exceeded
- Show green status in UI for quota exceeded accounts (normal state)
- Show '余额不足' as unschedulable reason instead of '已暂停'
- Simplify resetDailyUsage() to only check quotaStoppedAt field
