Root cause: CDC sync order issue caused referrerAccountSequence to be null,
resulting in empty ancestor chain and all TEAM_LEVEL contributions going to unallocated.
Changes:
- buildAncestorChainFromReferral: Uses ancestor_path (contains complete user_id chain) to build upline chain
- getDirectReferrer: Gets direct referrer using ancestor_path as fallback
- findAncestorChain: Updated to use ancestor_path when available
