Alexis Bruneteau 8be804f7c6 fix: Query PoA validators for blockchain state instead of local blockchain
Problem: The GET /api/votes/blockchain endpoint was returning the local
blockchain manager data instead of querying the PoA validators where votes
are actually being submitted.

This caused votes to appear successfully submitted (with block_hash from
validators) but not show up when querying the blockchain state, since the
query was hitting the wrong data source.

Solution: Update the /blockchain endpoint to:
1. First try to get blockchain state from PoA validators
2. Fall back to local blockchain manager if PoA unavailable
3. Add detailed logging for debugging

This ensures the blockchain state matches where votes are actually being
stored on the PoA network.
