feat: switch billing to ListSplitBillDetail for accurate project spending
- BillingService now uses ListSplitBillDetail (split bill) instead of ListBillDetail (bill detail) - the latter shows Project='-' for Seedance pay-as-you-go products - Added get_spending_all_projects() for batch query (avoids N+1 API calls) - Scheduler optimized: single API call fetches all project spending - Verified: amounts match Volcengine console split bill page exactly - Updated research report with billing API findings Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
