Overview

Combines vote counts from a parent voting session and all its finalized pre-vote children.

Pre-vote sessions are always finalized before the parent session starts, so their data is always read from DB snapshots (voting_contestant.vote_count / unique_voter_count). The parent (live) session reads from Redis when still running, DB when finalized.

Returns an array of rows keyed by show_contestant_id, each containing:

- contestant_id       VotingContestant.id from the live session
- show_contestant_id  ShowContestant.id
- vote_count          combined total across all sessions
- unique_voters       combined total across all sessions (per-session sum, not deduplicated)
- session_data        per-session breakdown array; session_data[0] is always the live session
- confirmed_rank, eliminated, name, contestant_number
