fix: use account status for balance records instead of hardcoded 'active'

- Modified sync service to pass account status to balance persistence
- Updated database service to use account_status from balance data
- Fixed 8 balance records that had incorrect 'active' status
- All balance records now have consistent 'READY' status matching accounts
- Future balance records will inherit correct status from account data
