refactor: split block handler into C1–C4 with allCandidatesKnown and candidate cleanup

Split the monolithic PollResultPoller into four specialized block handlers:
- C1 (ContractPoller): RPC multicall for non-deterministic generators only
- C2 (CandidateConfirmer): API confirmation + candidate deletion after promotion
- C3 (StatusUpdater): API status polling for open discrete orders + expiry
- C4 (HistoricalBootstrap): one-time owner fetch at live sync start

Add allCandidatesKnown boolean to conditionalOrderGenerator so C1 skips
generators whose UIDs are already known. Unify backfill and live creation
handlers to both use UID pre-computation for deterministic types.
